Attention Avi Fans

I recently read Avi for the first time, mostly to find out what this one-named author was all about. I was stunned to learn how many books he's written, and how many different genres he's tried -- and even more surprised to learn that he's done all of this despite a learning disability. Clearly, an inspiring figure.

But what I'm really excited about is the reader response option at the end of the profile linked to above. I'm dying to know which Avi book I should take up next. If you're an Avi fan, contribute a review of your favorite book now.
