An unexpected phone call heralds a new challenge for Mercy. Her partner Adam’s ex-wife is definitely in trouble, on the run from a stalker. Adam isn’t the type of man to carefully turn apart a person in need-and Mercy understands it. But with Christy holed up in Adam’s house, Mercy can’t shake the sensation that something about the situation isn’t right. Soon her suspicions are confirmed when she learns that Christy gets the furthest thing from good motives. She wants Adam back, and she’s willing to do whatever needs doing to obtain him, including turning Adam’s pack against Mercy. Mercy isn’t about to stage down without a combat, but there’s a more dangerous threat circling. Christy’s stalker is greater than a poor man-in fact, he may not be human being whatsoever. As the bodies start turning up, Mercy must place her personal problems aside to handle a creature with the energy to rip her whole world apart.
