Now she's a science experiment harboring a massive secret and running from those who want her power for their own vendettas. Stuck in a violent game of cat and mouse, Arie spends every moment evading Mr. Sark-the man representing the organization that would do anything to get their hands on what she's hiding. Sark is driven, cruel, and desperate to prove himself, and every day he gets closer and closer to unraveling everything Arie is trying to protect. One mistake on Arie's part drags a civilian named Erika into the game. Arie is horrified to find Erika involved in Sark's bloody hunt, and grapples with how to save them all. But Arie can't do this on her own. She needs some help if she's going to survive the secret looming over her head.Walls crumble and lines between friend and enemy are blurred as Arie struggles to decide who to trust while trying to protect her secret and those she loves, knowing not everyone-including herself-can survive.
