The much-anticipated third title in an epic adventure series from husband-and-wife team, John Parke Davis and NEW YORK TIMES bestselling author, Carrie Ryan. Beautifully illustrated by Todd Harris.

Fearless adventurers Marrill and Fin have just barely stopped the Iron Tide and the evil wizard Serth from destroying the Pirate Stream. Now they're on a mission to find Fin's missing mother, but before they can blink, Fin's people have found him - and they're not as friendly as he'd hoped. In fact, they're after a powerful wish orb that could resurrect the treacherous Iron Tide and end the world as we know it.

Without their captain Coll and wizard friend Ardent to guide them, are Marrill and Fin brave enough to take on the magic (and evil) of the Pirate Stream on their own?
