After being on the run, Ariane Tucker finds herself back where she started-under the cruel control of Dr. Jacobs, head of the research facility that created her. Now she must participate in the upcoming trials; a deadly competition pitting her against other alien hybrids, each representing a rival corporation.

But Ariane is no one's weapon. She is prepared to die if it means taking down those involved in Project Paper Doll. They destroyed all that she holds dear, including Zane Bradshaw, the one person she trusted and cared for the most-the person she was forced to leave behind, bleeding and alone.

As her plan takes shape Ariane will need to depend on, now more than ever, the other side of her heritage-the cold, calculated instincts born from her alien DNA. With Zane gone she has nothing left to lose.
