Reeling from betrayal at the hands of the Whispers, Renata Convida is a girl on the run. With few options and fewer allies, she's reluctantly joined forces with none other than Prince Castian, her most infuriating and intriguing enemy. They're united by lofty goals: find the fabled Knife of Memory, kill the ruthless King Fernando, and bring peace to the nation. Together, Ren and Castian have a chance to save everything, if only they can set aside their complex and intense feelings for each other. With the king's forces on their heels at every turn, their quest across Puerto Leones and beyond leaves little room for mistakes. But the greatest danger is within Ren. The Gray, her fortress of stolen memories, has begun to crumble, threatening her grip on reality. She'll have to control her magics--and her mind--to unlock her power and protect the Moria people once and for all.
