While cracking the case of a cold-blooded serial killer in Las Vegas, Dr. Charlotte Stone comes close to losing the one thing she never thought she'd miss: Michael Garland, the ever-present, fatally sexy ghost who goes wherever she does. When Michael is wounded by a hostile specter, Charlie only barely saves him in time. Though she'd never admit it out loud, nearly losing Michael has made her realize just how head-over-heels in love with him she's fallen. And since Michael seems to have made a habit out of saving her life, despite the toll it's taking on his not-so-immortal soul, keeping him around means staying out of trouble. Not so easy when FBI Special Agents Tony Bartoli, Lena Kaminsky, and Buzz Crane need her help solving a particularly gruesome case - while only Tony knows about her ability to see the ghosts of the recent, violently departed, the whole team knows Charlie's the first one to call to catch a serial killer. Can Charlie track down the killer without jeopardizing her own life - or Michael's?"
