The mystery revolves around a rare edition of The Wizard of Oz missing from the local library. When Becky is accused of stealing it, she and her twin brother Toby set out to catch the real thief and prove her innocence. Clues cleverly hidden in four other books lead to a hidden treasure—and a gripping adventure.

Behind the Book

Avi writes:

Sometimes a sequel is not a sequel. I had written No More Magic and it was doing well, so I decided I should write another mystery with the same characters. Liking maps, I came upon an atlas of fantasy maps. That’s the basis for the story. So I wrote it, but my editor chose not to publish it. I put it away for a while, but when another editor asked me to write a mystery, I took that old book out, and completely rewrote it—including the main characters—and that rewrite became Who Stole the Wizard of Oz?

Review
