Dr Charlotte 'Charlie' Stone is a psychiatrist who explores the darkest territory of all: the hearts and minds of serial killers. It's a job she's uniquely suited for, thanks to the secret talent that gives her an uncanny edge - Charlie can see the spirits of the dead. This blessing - or curse - gives Charlie the power to hunt down madmen and murderers. It's also turned her love life upside down by drawing her into a hopelessly passionate relationship with the lingering ghost of a charismatic bad boy.

But there's little time for romance when murder comes pounding at Charlie's door in the form of a terrified young woman fleeing a homicidal maniac. Saving her life places Charlie squarely in the sights of a sadistic predator nicknamed 'the Gingerbread Man.' Matching wits with this cunningly twisted opponent will require all of Charlie's expert skills. But even with her devilish 'guardian angel', not to mention her favourite flesh-and-blood Federal agent Tony Bartoli, watching her beautiful back, the Gingerbread Man's horrifying grin might be the last thing Charlie ever sees.
