Looks to me you enjoy pretty much any well-written book. I don't have a preference, really, I just read whatever.
Anyways, some suggestions at the top of my head:
1) Angela's Ashes - Frank McCourt (Autobiography, so obviously all about character development, quite sad at moments, a very good read)
2) To Kill a Mockingbird - Harper Lee (Literary classic, you've probably read it, but in case you haven't, please do)
3) My Name is Red - Orhan Pamuk (Mystery with a touch of romance, an intriguing read)
Better any suggestion than no suggestion, right? Still though, those are good books, do read them if you get a chance.
