If someone saved your life would you do anything to help them?  Would you let a pint sized spirit (dybbuk) live inside of you (for a little while) so he can get the truth out of a German soldier who killed him and other defenseless children?  What if your girlfriend threatens to call off the marriage because she thinks you are acting too strange?  What if the dybbuk steals your spotlight as you entertain audiences as a ventrioquist?  Would you want an exorcism?  

The Dybbuk has a name.  It is Avrom.  Because Avrom knows the truth, he feels he must share that truth with as many people as possible.  He needs a body in order to accomplish his mission.  Freddy has a career as a ventrioquist but it seems to be at a standstill since he can learn to talk without moving his mouth. 

If they work together can both of them succeed?

Even though this is a book with a ghost, it is not a mystery.  It is not even scary.  It is funny, light, and powerful all at the same time. 

Sid Fleischman uses humor, an interesting plot, along with true facts about the holocaust to present a message that needs to be remembered.
