In the rubble of a massive explosion that rocked Philadelphia, bones are discovered beneath the remains of a row house.

Assistant Chief Medical Examiner Trudy Beasley prides herself on providing answers and closure to victim's families, but the mystery surrounding the skeletal remains is something she's never seen before. Could whoever did this still be loose in the city? Trudy's instincts demand she pursue the truth.

Forensic anthropologist Benjamin Roberts disagrees. Ben sees the puzzle as an academic challenge, not a legal one.

As the investigation progresses, Trudy and Ben are pulled closer together, until their professional relationship crosses the line of professionalism and they find themselves in each other's arms. Will their newfound romance survive when someone is willing to kill again in order to keep secrets buried along with those in the row house disaster?
