Liar - Justine Larbalestier

Liar is the story of a teen girl, Micah, who just can't stop lying.  She lies about her sex, she lies about her boyfriend, she lies about her dad, and lies about her life.  When her boyfriend winds up dead, she needs to stop lying and confront what really happened. That is if she hasn't lied so much that she can't remember the truth anymore.

Why Read - It was a new teen fiction book in the library I work in and it looked interesting.
