I'm not usually a sci-fi reader but I just finished Roadside Picnic and I loved how everything to do with the aliens was never really explained or understood. Are there other sci-fi books that treat the sci-fi elements as casual givens? by Ravenq222 Related: Suggest me a gut wrenching romance book. A romance/mystery/thriller book Suggest me books similar to Lessons in Chemistry Longer book series with the feel of the Hunger Games, but ideally not YA? History of Japan books?
