Eighteen years ago, a group of men killed Regan Miller's boyfriend and tried to kidnap her daughter, Kelsey. Since then they have lived in hiding, always vigilant and never getting close to anyone.
When Kelsey goes away to college, Regan finally begins to relax. She even starts to think she can have a real relationship, perhaps with her flirtatious neighbor, Tyler Sloane. Then Regan is attacked again.
Desperate to get to her daughter, Regan accepts Tyler's help—despite her suspicions about him. She knows nothing about Tyler but he knows a shocking amount about her past. Tyler can't tell her what he knows or who he works for, but he insists she can't face her enemies without him. Tired of living in fear, Regan is ready to take the offensive, with Tyler by her side. But is she relying too much on a man she can't trust—and falling for him, too?
