I don't know if this counts, but when I was about 13I was very excited to find an enormous book in my favorite genre at the time, Battlefield Earth by L. Ron Hubbard.
It was the first book I ever put down in disgust without finishing. In the almost half-century since then, there are under a dozen that I haven't finished. Shows you just how bad it is.
I haven't read the entire book, but I've read like 10 pages of Fifty Shades of Grey when my then-girlfriend was reading it. Besides the story and subject matter, the writing itself is horrible.
I was far too young to read Animal Farm. I thought it was going to be like Charlotte's Web. I did not have any of the historical or political context for the metaphor. It just made me angry.
Left Behind. I'm probably a huge idiot for not realizing for the entire thing without knowing before hand what the context was, but I read it with the idea that it was some kind of apocalyptic sci-fi, and then only in the very last few pages of the book did it finally hit me in the face that it was religious doomsday bullshit. I do have to compliment it for the storytelling and world setting, but holy shit was I disappointed with the end direction 🤦
Wizard’s First Rule by Terry BrooksGoodkind. I suffered through the whole thing because I was young enough that I thought that’s what you should do when you’ve started a book, but I was also old enough to know that it was very bad. I’ve heard many people say they read it as teens and loved it, but I assure you, it does not hold up.
I can't really remember of all time, but recently I started reading Dune: Messiah, and I had to stop reading it was so bad. I might be in the minority but the tonal shifts, changes in character attitudes, and jumping right into these assassination plots, all of it just came out weird and misplaced. Definitely did not slap with even 1/4th the power of Dune.
"The Cat Who Walked through Walls" by Robert Heinlein...
Now Heinlein is usually kind of obnoxiously sexist so having a book that opens with what appears to be an actual female character with not just more personality than a playboy magazine centerfold, but what seems like big dick energy action heroesque swagger felt FRESH. Strong start as you get this hyper competent husband and wife team quiping their way through adventures in the backwoods hillbilly country of Earth's moon with their pet bonsai tree to stop a nefarious plot with some promised dimensional McGuffin.
Book stalls out in the middle as they end up in like... A swinger commune. They introduce a huge number of characters all at once alongside this whole poly romantic political dynamic and start mulling over the planning stage of what seems like a complicated heist plot. Feels a lot like a sex party version of the Council of Elrond with each of these characters having complex individual dramas they are in the middle of resolving...
Aaaand smash cut. None of those characters mattered. We are with the protagonist, the heist plan failed spectacularly off stage and we are now in his final dying moments where we realized that cool wife / super spy set him up to fail like a chump at this very moment for... reasons? I dunno, Bitches amirite?
First time I ever finished a book and threw it angrily into the nearest wall.
Catcher in the Rye. I try it again every couple of years just to see if I can relate to it, and nope - it's still just as stupid as the first time I read it.
Canonical answer is The Homecoming Saga by Orson Scott Card, since it turns out that if the good guys have a mind controlling god computer that's always right on their side it gets really hard to have meaningful conflict.
Great story, but the writing was exceedingly dull, apart from the first chapter. I even tried getting through it via audiobook and still only made it halfway through. It's just a chore.
Mein Kampf. I read it when i was still a succdem, expecting some genius rant that converted people en masse to nazism. Instead it was barely coherent disgusting racist drivel. I guess this book didn't make anyone into nazi, it just given nazis what they would like to read. This and the fact nazi state bought huge amounts of it to distribute, making Hitler richest writer in Germany.
I'm sure I've read worse but one that stands out as making me question the time I put into reading it is Out of the Dark by David Weber. I go into it expecting a military sci fi, and for the vast majority of the book that's what you get - aliens invade Earth and plucky humans resist etc etc. The aliens however have more reserves and air superiority so are slowly winning as the end of the book approaches, at which point you expect the main characters to pull a rabbit out of the hat and do something different. Except that's not what happens.
spoiler
What actually happens is that Count Dracula appears out of (almost) nowhere and flies with a bunch of vampires up to the alien spaceships to kill the aliens, winning the battle for Earth.
I was definitely not satisfied with this ending, even if there was some foreshadowing earlier in the book that made sense after knowing this was a possibility in this universe.
The sookie stackhouse books that got turned into true blood have such a fun premise but are appallingly written. A friend and I used to play the audiobooks at parties for laughs.
The first 5 or so of Trump's books. No meaningful lessons in business to be had. Just him bragging about people he knew, people he'd screwed over, how good he thought he was at pretty much everything. How he got back at anyone who crossed him. Insufferable. I knew he was one of the worst people ever before he even mentioned getting into politics.
And in those 5 books, he probably name-dropped every New York socialite he ever met. It's consistent with his whole image of self-worth and needing to look and feel important. You know who he didn't mention? Someone we've seen him with in several photos? Who he definitely would have mentioned if there wasn't a reason not to? Jeffrey Epstein.
It's been quite a while since I've read it, so this may not be a fair assessment. But, I fucking hatedThe Catcher in the Rye. I wasn't even required to read it for school or anything, I just did. Perhaps I just found Holden to be insufferable. I think that was the point, but it did not make it a particularly enjoyable or insightful read at all, save for the overwhelming supertext of DO NOT BE LIKE THIS GUY. The part where he hires a prostitute and just cries in front of her really stuck in my mind. That was when it really sunk in for me that someone read this book and decided that Holden's views were so accurate that he had to go shoot John Lennon with a gun for being phony. Almost unbelievable.
50 Shades… terrible writing and the sex was boring AF. The books were recommended to me. I couldn’t get through the first one. Time I’ll never get back.
I was assigned Ethan Frome in a high school lit class and to this day I think it is one of the worst books to assign to emotional, angsty, experience-limited teens.
I also don't understand why Romeo and Juliet is the go-to Shakespeare work that we default to.
How do we handle complex romantic relationships? Suicide / attempted suicide, of course! Just what every teen needs to hear /s
A Heartbreaking Work of Staggering Genius by Dave Eggers. If you could distill pure insufferable smugness into a liquid, this was him squirting it into your mouth while you’re not paying attention and laughing at you while you sputter and gag.
War and Peace. Heard so many good things about it. Despite everything, went in not having super high expectations.
The whole book turned out like a reality tv show. All the characters had some petty drama that they blew out of proportion. Hundreds of pages where nothing really happens, people just complain or bad mouth other characters.
The Alchemist, I had to read it for a community college class. It's probably the most predictable book I've ever read, but not in an entertaining way. Just painfully boring.
I read Siddhartha for highschool a couple years before, I would say that the books are almost identical, except I liked Siddhartha more.
You want a book with similar themes but actually amazing? The wizard of Earthsea.
I know the books aren't literally the same. But the vibes feel very similar. I want to say they have very similar structure, but my memory doesn't work that great.
I've read a lot of books, but that one I literally remember nothing about. Not a quote, not a character, not the plot... All I remember is the cover was some weird abstract art piece with creepy eyes, my brain purged everything else about it book. Probably for my own sanity.
I am not sure about 'ever' (I am old and have been reading for over 4 decades now), but a book I hate-read recently was Foucault's pendulum by Umberto Eco. It is meant to be a satire on conspiracy theories and as such it is still a relevant book after 35 years or so. However, the point of satire is to get to the point eventually, preferably within 500 pages. It was pompously written and sometimes felt like a showcase of 'look how much I know!'.
I feel a bit bad saying this because there are definitely worse books but this one stuck with me as the premise sounded really interesting but the book was nothing like it.
There is a review on goodreads that sums it up pretty nicely.
Literature about literature, books about books, literature about books, books about literature, literature about literature, books about books, ...
The old man and the sea. I learned to hate reading because of assigned books in school and this was the one that drove that hatred most. At times in my childhood I enjoyed reading a couple of novels, but assigned books absolutely destroyed any interest I had. Also having religious cult like parents that always had something stupid to say about reading had a major impact.
I forced myself to finish it at the time, but I hated every single moment. They were all bad people and I had zero sympathy for any of the kids or adults, except for the one girl who died at the end. Obligatory Rowling can jump off a cliff too.
Probably Don Quixote. It started off really well, but it devolved towards the end into this long-unending self-referential rant full of name-drops and exposition, and I could barely follow any of it and pushing through that was a huge chore.
I later learned I had read a bad translation, and that there is one good translation out there I should try, but the whole thing has left a bad taste in my mouth and I don't want to go anywhere near that book again.
I haven't read a whole lot, but so far: Madame Bovary. We had to read it in high school, because it was culturally significant and because it caused a large amount of controversy when it came out due to its subject matter. When I was reading it though, it felt like I was reading a literary version of every TV soap opera ever. It was a slog to get through and I was bored and annoyed throughout.
Revelation Space by Alastair Reynolds. I am usually a huge SciFi fan, but I like the genre for it's ability to reflect on humanity by extrapolating on current technologies/trends or comparing our culture to unique alien ones.
Revelation Space was technobabble and descriptions of weapons for pages upon pages, and it was totally devoid of any philosophy or reflection on humanity. I never DNF a book, but this one I almost gave up on.
True, he straight up admits many times in the books that he would lie about his wealth so that other people would work with him. I assume that came out during his fraud case in NY.
He had a few deals that worked out - all starting with dad's money. He managed to squander 4 out of 5 of everything he tried. Casinos in Atlantic City, Trump University, Trump Steaks, Trump Ice, Wollman Rink, etc. It's a long list. But the 1 or 2 that worked is why he has any money at all. If I remember correctly, it's mostly the golf courses and an option he bought in the 70s for an old railroad yard in lower west side Manhatten I think. He really fucked someone over on that one. He bragged about how much he screwed them for pages and pages. Like it brought him more joy to fuck someone over than it did to have a success. He's a complete psychopath.
There are books I started and did not finish that I do not remember. However, there a few that I finished but hated. The worst was:
Reverie - this was a lgbt book club thing in Libby. The protagonist was a whiny incapable teen that never redeemed themself. I kept thinking it would get better and it never did. Things resolved because magic, so poor/lazy writing.
I don't even remember the title, but it was written by Clive Cussler.
It was the dullest, most stereotypical adventure book with the bog standard protagonist and plot, with no interesting twist or unexpected event at all.
I tried reading two different series from Stephen R. Donaldson, and it seemed to me he was somehow unable to write a book without a horrific rape. I just stopped reading the first book in each case because I felt like they were salacious and hateful.
Worst book I've quit is Seveneves by Neal Stephenson. What a horrible book!
Worst I've finished is Grapes of Wrath by John Steinbeck, immediately followed by Of Mice and Men by John Steinbeck. I'll throw in a special mention for The Scarlet Letter and The Great Gatsby. All terrible books that I finished only because they were required reading in school.
I tend to quit books if I don't find them very good. One I did finish that I fucking hated was The Girl on the Train. All of the characters were fucking insufferable.
Probably not the worst I ever read, but whenever a question such as this comes up my mind immediately goes to one of the Tarot books by Piers Anthony. I don't remember which one, it was just in a pile of books people left in a dorm one time and I had nothing to read.
I finished it, but I can't tell you anything about it other than the vague recollection that I hated it.
Z for Zachariah. I read it when I was like 15 for school. Man I remeber feeling the book is like a farming manual when they tried to survive after the nuclear war. The older man trying to rape the other 16 year old girl survivor also made me super uncomfortable. Maybe it would be better if I read it now. I just remeber it being a drag.
"Meteor" by Dan Brown (could be a different name in the original language). It was the first time I read something that was bad. Up until then book were cool and fun and interesting. It was a puzzling experience.
Edit: it's called "Deception Point" in the original.
Was chosen by my Community College English professor and it was the most mind numbing thing I've ever had to read. It was translated from German, so there are multi-page, run-on sentences that haunt me till this day.
Anything by David Foster Wallace.
Smug, preachy stream of consciousness garbage that is then annotated to oblivion by more stream of consciousness smug preachiness.
I suffered through it because I love the franchise so much and it wasn't that long but holy shit, I was the writing quality of a grade schooler but with added unnecessary and gross romance between two children.
Bill McKibben's Enough is on my shelf purely so I can flip through it and get mad. A dense little paperback on how technology and progress should just stop. Not even return-with-a-v to some imagined utopia, like Ted Koweveritspelled. Straight-up 'change might be bad, so let stop right here, the moment this book is published.' Pushed with such flimsy arguments that my copy is about half post-it notes, by weight, from the month I read it for a philosophy class. They stop halfway. I just didn't consider rebuttal necessary past a certain point. You don't have to eat the whole turd to know it's not a crabcake.
The book of a thousand nights and a night. Went in knowing it was the original inspiration for Aladdin. Was not prepared for a litany if short stories about sex and racism
Sirens of titan. Well, Vonnegut in general. His stories are fine, probably ground breaking for the time in the sense of exploration, but the characters have no depth. It's like reading a book about npcs. Then there's the misogyny. Women are simply livestock kept around for breeding in this one, worse than an afterthought.
I don't think it's valuable to read even from a historical standpoint. Wiki synopsis would be suggested.
I've read so many it's hard to say but recently the Star Wars book about Phasma stands out (most of the books since Disney took over are not great). Also a series someone on Reddit recommended that turned out to be basically a guy writing down a game of Stellaris. I don't remember the name of it but it was awful.
