Untraceable

Alexandra Lovell is a private investigator who uses computer skills and cunning to help clients vanish and start over safely. One of them, Melanie Bess, was running from her abusive husband, a cop. Now Melanie has disappeared for real, and Alex fears the worst.

Alex starts digging into what happened to her. She draws on the Tracers, an elite team of forensic scientists, and on an Austin PD detective, Nathan Deveraux. He is jaded, and she is drawn to him.

Nathan is a homicide cop who holds that without a body there is no case. He would rather think Alex is wrong about a murder. But his instincts, and a strong pull toward her, keep him on the investigation.

This is romantic suspense, with a missing-person search that turns into a possible homicide inquiry. As evidence builds, a grim picture forms, and the case proves to run deeper than either of them expected. Each step closer to the truth also puts Alex at risk of being the next person to vanish.
