I read my first two books ever and looking for book suggestions! I love strange sci-fi like Annihilation, Solaris (movie, but ordering the book right now)

I'm looking forward to ordering more books, I just finish my first books ever:

• Annihilation
• Lord Of The Flies

I've enjoyed both of them so much. After searching, I've ordered the following:

• Solaris
• Roadside Picnic
• Rendezvous With Rama
• Authority (Southern Reach Series #2), I'm going to read the entire series, I loved the first one so far

What other books would you suggest?

I come from a movie background and looking for themes similar to some of these movies:

• Primer (very realistic approach to time traveling, no back to the future bs)
• Pi (mathematics and how PI is everywhere in the world, somebody uses it to predict the stock market)
• Take Shelter (guy believes something horrible is going to happen, decides to build a bunker, it's up to you if you believe him or not.
• Donnie Darko (Guy wakes up in the middle of the night and sleep walks to a golf course where a person dressed in a giant bunny rabbit suit tells Donnie the world will end in a particular amount of time, 28 days)

I tried an Asimov book, but I felt it was too "Space Opera" for me, I don't like that, I can't stand Star Wars, or similar Fantasy settings like that. It was called The End of Infinity.

Really looking for strange themes. I've never read a single line of Lovecraft, I'm considering some of those books as well.

Thanks!
