Reading for fun is good.
I agree with @notsmokinjo , the Odd Thomas books are great fun to read.
After reading this thread, I was thinking of highly cerebral books to suggest (The World According to Garp, The Unbearable Lightness of Being, etc.) but it didn't feel right
Bitter Blood is a highly detailed true crime novel of some really weird things that happened in my hometown of Greensboro, North Carolina.

Replay by Ken Grimwood is an interesting sci-fi about time travel.

Just some random stuff that entered my mind. Nothing groundbreaking but interesting reads.
