Debut romance and science fiction thriller by Claire Riddick.

Caffrey Hansen aids a dying man in a traffic accident on a busy Atlanta street, and is given a tiny disc that can only be read by an alien machine. In a matter of hours, she becomes an unwilling messenger on the run for her life, driven to find people she has never met, intent on protecting a secret imbedded in her brain. The only man who can extract it, is dead. The only man who can protect her, is convinced she's a spy with programmed memories, and a threat to the last hidden network of people who are still in control of their minds.
