A dying friend, a terrible bargain, an underwater quest, and dangerous magic . . . this thrilling adventure picks up right where Children of the Fox leaves off. Fans of twisty, clever stories like The False Prince and Ocean's Eleven will love this newest series from Kevin Sands, author of the bestselling Blackthorn Key.

Rule number one: Never mess with magic. Even so, a life-or-death situation calls for Callan and his criminal friends to make a deal with the Eye—the sinister, sentient artifact they stole from a sorcerer. It's Lachlan's life in exchange for a future task, and the gang has no choice but to agree.
 
But even as Lachlan is resurrected, it's not without cost. Through the Eye, Callan can see a tiny purple stain inside Lachlan's soul, which will eventually consume him. The cure—and their part of the deal—lies with the Dragon's Teeth, a pair of swords with extraordinary powers, and the search for them leads the thieves on a quest that will unravel the mystery of the Eye. Old friends, new betrayals, and an even more daring break-in than the last culminate in a confrontation that will take all the gang's skill and power to resist—or they'll die trying.
