Desperate to break the intimacy of their telepathic link, he becomes the enemy and begins to hunt Kaitlyn's group. Rob is determined to destroy Gabriel if he has to... but Kait can't let that happen. On her own, she leaves her friends and returns to the Institute, pretending to join Mr. Zetes. But when her reckless gamble goes wrong, will Gabriel save her--or betray her again? And when the final battle comes, will Kaitlyn choose the light with Rob or the darkness within Gabriel.
