But figuring out how to control his magic is a lot harder than he hoped. And there's no time to lose! A terrifying new threat is surging through the Underworld. If Montgomery is going to help save his friends from the fearsome soldiers of Atlantis, he needs to learn fast - even if it means forging the most unlikely of alliances.
