Deadman's Bluff (Scene of the Crime Series) by Carla Cassidy

FBI agent Seth Hawkins was on a mission to catch a serial killer. Yet his only lead-a mysterious azure-eyed beauty found buried alive in the local sand dunes-had no memory of how she'd been abducted. Or anything else about her identity.

The only thing Tamara Jennings knew for sure was the undeniable attraction she felt for the strong, handsome man who saved her life. It wasn't long before their passion flared out of control. But as memories of her forgotten past returned, would they lead her to the killer-and to a life she could share with Seth?
