"Will keep readers on tenterhooks as it reaches its gratifying end." --Kirkus Reviews

In the thrilling finale to bestselling author Abi Elphinstone's The Unmapped Chronicles, a young orphan rises up to stop the evil harpy Morg once and for all.

Eleven-year-old Zebedee Bolt is on the run. Again. Only this time, it's not the police who find him. It's an evil harpy called Morg. And when she hauls him into Crackledawn, an Unmapped kingdom that conjures sunlight for our world, Zeb discovers running away only gets you so far.

When magic's involved, you've got to pick a side. And though Zeb vowed he wouldn't trust anyone ever again, he didn't expect to stumble aboard The Kerfuffle, an enchanted boat belonging to a girl called Oonie and her talking chameleon, Mrs. Fickletint.

Suddenly, Zeb finds himself on a voyage complete with silver whales, fire krakens, and underwater palaces. Can he muster up enough trust in others, and in magic, to summon a dragon, find the Ember Scroll, and defeat Morg once and for all?

This is a story about saving the world but it's also a story about trusting friends--and chameleons--even when kingdoms are falling apart.
