Justine Silver's best friend, Mary Catherine McAllister, has given up chocolate for Lent, but Jussy doesn't think God wants her to make that kind of sacrifice. So she's decided to give up being Jewish instead. Jussy's bedroom closet has become her confessional, where she pours out her sins to her teddy bear and takes Communion using grape juice and matzo. But when her beloved grandmother, Bubbe, suffers a stroke, Jussy worries that her religious exploration is responsible. Worse, Jussy must suddenly contemplate life without Bubbe, the one person who seemed to understand her. Now Jussy feels she must decide once and for all who she is, and where she fits in.
