To save her life from a deadly blood oath, a teen girl must steal a long lost magical relic and betray a handsome prince in this epic YA fantasy novel. The kingdom of Heartwood is sinking into the sea, but Kyra doesn’t have time to worry about that. She’s too busy trying to protect herself and her sister. A thief known only as the Shadow, Kyra has inherited a deadly blood oath that forces her to steal powerful relics for the villainous crime lord Vulcan. Fortunately, Kyra has a gift, a magical ability to erase the memories of anyone she touches. But magic is illegal in Heartwood, and magic users, or ‘saps’, are punished with execution. And if anything were to happen to Kyra, the oath and its deadly consequences would pass to her beloved younger sister, Jex. So when Kyra gets the opportunity, she jumps on the chance to strike a new bargain: if she can bring Vulcan the three pieces of the Triad, a legendary relic that gives the wearer power over their enemies, he will release her from the blood oath. Vulcan agrees, but if Kyra doesn't deliver, her oath will come due and her life will be forfeit. And worse, finding the Triad involves working with Prince Archer, a childhood friend who has grown into a handsome, devastatingly kind prince, one who is dead set on saving the kingdom, no matter the cost. The closer they get, both to each other and to the Triad, the more Kyra's secrets and betrayals start to burn. But Kyra can’t let her heart get in the way. Because saving Jex means betraying Archer and leaving Heartwood to fall.
