An intruder has seized control of Lexi Matthew’s mind, putting those closest to her in grave danger.
When someone snakes into Lexi’s head and threatens Jack’s life at Lexi’s own hand, she must quickly decide: leave Jack and the web of lies and controversial medical science behind in order to protect him, or stay and fight to regain control of her own mind but risk Jack’s life.
Before Lexi can choose, she’s immersed into the underground world of the International Intelligence Agency, where she discovers the world of cloning and mind control is much larger than she and Jack ever imagined and is growing bigger and more dangerous.
As the band of teenage human clones uncovers more of their supernatural abilities, a dominant force inside the IIA is at work to take over their powers. Can Lexi stop the person who has invaded her mind before the IIA captures them all, or will she sacrifice herself to save those she loves?
