That's... a very,
very broad inquiry, even with the preferences listed. If you like historical fiction/World War-era books, then there's quite a lot to choose from. Some of my favorites are
All Quiet On the Western Front by Erich Maria Remarque and
Farewell to Manzanar by Jeanne Wakatsuki Houston and James D. Houston. These are both
extremely depressing stories, but if you're into that, then by all means, give them a read. If you haven't already, you should definitely also give
The Diary of Anne Frank a read since it's the most well-known and prolific piece of Holocaust-era literature. If you want something a bit more contemporary that takes place at around the same time period (but isn't necessarily related to the war itself), I've been hearing good things about
Before We Were Yours by Lisa Wingate, which is about the controversial Tennessee Children's Home Society--feel free to Google that if you
really want to have a bad day. It's a very upsetting topic. I haven't read the book yet, personally, but it's inspired an entire genre of knock-offs on Amazon, so it must have done something right!
Beyond that, I'm not really sure I can gauge your interests very well with the information you posted. I can understand, though, that books are a particularly difficult medium to get into, and it can be hard to truly assess your own feelings for them. Things that you enjoy in movies and shows may not necessarily translate into books you like and vice versa. For example, I love horror books--though I surprisingly haven't read a lot of them--but don't care for horror movies. Meanwhile, one of my favorite movies is
Jurassic Park, but while I enjoyed the book, I have a difficult time enjoying books in the same genre as
Jurassic Park.
Unfortunately, the only way to know what you enjoy is to start somewhere. Hopefully these recommendations will help. If you're into classic literature as I am,
Project Gutenberg will soon become your best friend, so feel free to give that site a browse as well.
