Countdown by Iris Johnansen

Jane is running for her life. Her adoptive parents, forensic sculptor Eve Duncan and Joe Quinn, of the Atlanta PD, can't help. The FBI can't help. No one can. Except a man who may be more dangerous than those pursuing her. A smuggler, a con man, Mark Trevor had his own mysterious reasons for wanting to keep Jane safe from a relentless killer and a two-thousand-year-old mystery that could rock the modern-day world. For the past is returning with a vengeance that knows no mercy. The countdown has begun, and it's closer to zero than anyone thinks.
