The wicked-ly good New York Times bestselling series continues with some new perils in Oz.

Ava is getting a little tired of told when to use her magic... and when to leave it to the adults. Case in point: When a helpful curse is broken, her friend Henry goes physically from being a small boy to being a big giant. And, even worse, he's in the cafeteria at the time, and he's now stuck inside, too big for any of the doors. Ava wants to help -- but the head of the School for Wicked Witches tells her and her friends to let the teachers figure it out.

This isn't good enough for Ava. She, Crow, and Tinabella are going to do whatever they can to help Henry. They've even found an ally in an older girl named Angelica, who Ava thinks is really cool... and who Tinabella doesn't trust. When Ava's magic wobbles at the exact wrong time, she and her friends are suddenly in more trouble than ever. But will the way out be a good one... or will it lead to something wicked?
