After seven years on the run, Dr. Kara Cantrell believes she and her son, Alex, are safe.

She’s wrong.

Kara settles in the sleepy town of Zorro, Texas, convinced that she and her child have escaped the sinister reach of a supernatural underworld. But the appearance of Damien Morgan, a dangerous, alluring man with superhuman abilities, upends her quiet existence. Damien realizes that Alex is a fledgling Sentinel, and Kara is a matched, psychic conductor for him. She wants nothing to do with him, refusing to revisit the hell she experienced seven years ago. But she has no choice, as her son is projecting his abilities, leaving him vulnerable to unseen forces. Not only that, but someone—or something—is murdering people in Zorro. Kara is forced to work with Damien, tapping into a mystical link that triggers desires both of them must ignore. But as they work together to protect her son and to track the killer, evil stalks them—reaching out with the touch . . . of darkness.
