An unexpected phone call heralds a new challenge for Mercy. Her mate Adam's ex-wife is in trouble, on the run from a stalker. Adam isn't the kind of man to turn away a person in need-and Mercy knows it. But with Christy holed up in Adam's house, Mercy can't shake the feeling that something about the situation isn't right. Soon, her suspicions are confirmed when she learns that Christy has the farthest thing from good intentions. She wants Adam back and she's willing to do whatever it takes to make it happen, including turning Adam's pack against Mercy.
