On advice of readership, I read Who Stole the Wizard of Oz? this week, and I have to say, this book kind of shines. I think it's because it's meant for younger kids, so some of the inconsistencies and over-simplicity don't bother me as much. It's a fun small-town mystery, Nancy Drew-light, and a lot of fun. So I guess Avi's still on the table after all.
