In the months since Benjamiah returned from his adventure in Wreathenwold, he has been dying to return to those labyrinthine streets. Desperate to find anything that will bring him to the impossible magic, the Minotaur, and most of all, his best--and only--friend Elizabella, he looks through his mother's things and finds a strange witchstone mask that leads him back. The only problem? Once the mask is on, it won't come off.

But Wreathenwold is not how Benjamiah left it. Nor are Elizabella and her father where he left them. Worse still, children have been disappearing, and no one knows where they are or who has been taking them. Benjamiah has to find Elizabella and, with the help of two new companions, undertake a series of magical trials to remove his mask and save the missing children of Wreathenwold before Midsommer ends and they are all lost forever.
