Reading across the age group

Okay, full confession. I love reading young adult (or middle grade) books. Harry Potter, Percy Jackson, and now, Truly Devious. It's fun to go back to high school and realize you're not the only one feeling out of place.

Shadow and Bone is a YA fantasy and I'm loving the second book in the series.

I love these books because of their reluctant hero main character. I'm just a kid. I'm not special, until you find out you have hidden talents that are more than you'd ever expected.

Your turn, favorite young adult book you read either back in the day or now, and why?
