Evil shadow ghosts known as soul collectors haunted her childhood nightmares, so Nashville PD criminal profiler Jillian Drew did everything possible to turn her back on her psychic abilities. But now her eccentric sister has been abducted and nothing in her criminology background has prepared Jillian for that tragedy – or for Benton Smith, the powerful and devastatingly attractive ghost of a Civil War officer and the only witness to Amy's abduction.

Fearful of the brazen specter, Jillian nevertheless needs him. Benton is her Gatekeeper, a spirit sworn to protect her from the soul collectors, who attack each time she unleashes her long-dormant psychic senses in an attempt to find her sister.

Yet she must somehow keep the devilishly seductive spirit at arm's length, for Benton's soul is at stake – and succumbing to his desires could have dangerous consequences for them both.
