I love, love, LOVE, Jodi Picoult books!
Here are some that I have read:
Nineteen Minutes
My Sisters Keeper
The Tenth Circle
Change of Heart
The Pact
Plain Truth
Nineteen Minutes is about a a nerdy guy who went into his highschool and killed 19 kids he disliked. (Alot like the Virginia Tech shooting, although the book came out before the shooting!)
My Sisters Keeper- (This was made into a movie.) About a girl who was born so she could give her sister with leukamina blood and other body parts she needs. When she becomes 13, she decides to sue her family to have permission to her own body. (This book is so sad, and I cryed during it! Awesome book!)
Nineteen Minutes and My Sisters Keeper were my favorite books by Jodi Picoult
