Linux, networking and security books recommendations

Hi! I’m looking for some book recommendations on Linux, networking and security. I’d rather they were 3 separate books, instead of an All-in-one. I know I can learn about this on the internet, but this is kind of my way of reading books. Some like thrillers, I like learning about tech what can I say haha It’s not for school or work, just something to expand my knowledge. Ideally, security and networking would start at fundamentals, and go beyond. In terms of Linux, I’m finishing “how Linux works” by Brian Ward, so something above that would we great! Thank you :)
