Matched by Alie Condie
Delirium by Lauren Oliver
The Absolutely True Diary of a Part-Time Indian by Sherman Alexie
The Percy Jackson series by Rick Riordan
The Lost Hero by Rick Riordan (but read Percy Jackson first!)
The Gone series by Michael Grant

If you like "chick lit," try anything by Sarah Dessen.
Crank by Ellen Hopkins

Life As We Knew It, The Dead and the Gone, and This World We Live In by Susan Beth Pfeffer
I hope I didn't overwhelm you! I'm a YA Librarian, so I spend a lot of my days ordering and recommending books!
