A novel by

After surviving a near-fatal accident, undercover agent Eric Caldwell wanted revenge. Falling for his beautiful physical therapist had never been part of his plan. Melissa Fagan was investigating the same mysterious medical research complex that he was. But she was asking too many questions, digging too deep.

Now someone wanted her dead - before she could discover the truth about her birth parents.

All Eric wanted was to keep Melissa safe and alive. But how could he protect her without blowing his cover, jeopardizing his mission...and risking both their lives?
