The brutal m******e of Artemis Crane's entire family mysteriously left her with no memories other than the s*******r itself—and some supernatural strength and healing. Now with incredible power that she hides and tormented by nightmares of the dead bodies of the family she once had, Artemis tries to live her life like a normal sixteen-year-old girl. Then, a lab accident causes her to slip into a coma only to wake up two years later to a strange old man at her bedside who claims to be the only doctor in the world who can cure her illness and protect her from the endless waves of assassins that have been trying to get rid of her since she went under. Terrified for her life and wanting some answers, now eighteen-year-old Artemis goes into hiding under the protection of the old doctor and, in the process of healing and getting back her memories, stumbles upon a secret that explains the target on her back and the power that now surges stronger than ever in her core.
