Dessa, Topper and Fisk arrive on the incredible flying island of Astaroth, where Dessa hopes to find her long-lost brother, Jared. Instead, she discovers a bizarre world beyond anything she could have ever imagined, where three children roam under the watchful eye of a mysterious and rarely seen man they call the Toymaker. Who are these kids, and how did they get here? And, if Jared is not on the Dark Island, where is he?

The Three Thieves series follows Dessa, Topper and Fisk—circus performers on the lam after trying to rob the royal treasury. But the thieves are also on a quest of their own: they are searching for Dessa's brother, abducted years earlier by the Queen's chamberlain. This latest installment is an exciting mix of mystery, friendship, comedy and escape—and a cliff-hanger that will leave readers hungry for more.
