Blank Confession by Pete Hautman

This was our January pick for book club and one of the year's favorites.  Shayne Blank walks into the local police station and confesses to killing someone.  It takes some frenzied page turning to find out what happened, revealing some very surprising answers throughout the mystery--not to mention some fascinating characters.  As we wrapped things up, more than one of us wished a character like Shayne Blank existed in our school community.
