Just finished The Pianist and im in search of something similar.

Its a classic i know, im a pretty new reader too so The Pianist was sooo fun to read. I generally liked the WW2 theme where the point of view was the victim. Do you guys have anything similar? Idk if there is a book like this but i would love to read the struggles of someone under enemy invasion, can be a chinese perasn agains japanese or a russiom person against germans.
