Some children are born unwanted. Darcy was left in an alley as a newborn. Mr. Cole found her. Raised her. Made her into something perfect-his favorite weapon, his deadliest assassin. She doesn't feel. Doesn't cry. Doesn't break. Until she finds a file in his office. Photos. Names. An address. Her family. The one that threw her away. Now Darcy wants answers. She wants revenge. She wants to understand why she was left behind. But Cole doesn't let go of his broken things easily. And the family she's found-a mother racked with guilt, a little sister who refuses to give up on her-they're in more danger than they know. Because Darcy isn't the only one looking for them. Sienna Vasquez, the girl who betrayed her, is back. A rival family is circling. And Cole will do anything to keep his masterpiece under control. But Darcy is done being perfect. She's done being a weapon. And she's about to show them all what a broken thing can become when she finally decides to fight for herself.
