But Quove's deadly agenda has finally caught up with Cade, and now he must leave his home and flee once more, this time to the legendary floating city of New Sanctaphrax. But even reuniting with his uncle, Nate Quarter, isn't the end of Cade's troubles - and now, more than ever, he must find the courage to defy his enemies, unite his friends, and unlock the secrets of descending.
