The killer is meticulous, making sure to wipe up even the smallest traces of evidence, but the Delphi Center experts are on the case. The local sheriff has a suspect all picked out, ex-Marine and current security expert Liam Wolfe. Despite all her digging, Tara knows very little about Liam when she shows up at his sprawling Texas compound, which serves as headquarters for Wolfe Securities, and she's surprised by her intense physical reaction to him. As she and Liam grow closer, Tara finds herself depending on his skills and expertise to help her track a killer. But when another body turns up, Tara must decide if she can trust the man who's quickly stealing her heart.
