Mac Argeneau knows immortals can be killed. Not with holy water or silver crosses, but by decapitation or being set on fire. So when Mac's house bursts into flames - with him inside - he's sure it was no accident. But who would want to kill a scientist specialising in hematology? There's a silver lining: a blonde investigator appears on the scene and sparks feelings in him that have been dormant for centuries. CJ Cummings is in town on a special investigation, but she's been waylaid by local police to deal with this arson case. The biggest mystery is how this sexy scientist has emerged without a burn mark on him. Sure, she'd love to see him without his lab coat, but she's got a job to do - despite his insistence that he needs a bodyguard and - he wants her. But when a second attempt on their lives puts CJ in harm's way, it's Mac who'll do anything to safeguard the woman who's destined to be his life mate.
