Normal young women go on dates on Saturday nights. Paranormal investigator Betty "Boo" Boorman goes on ghost hunts in Savannah, Georgia, America's most haunted city. She's more comfortable around ghosts than guys, anyway. A violent haunting forces Betty to team up with her rival ghost hunter, the arrogant Carter Lansford. When the violence is turned toward her, though, Betty knows she needs additional expertise. She enlists the help of a handsome stranger, who introduces himself simply as Maxwell, Demon. Betty's ghost hunting is cut short when she's threatened and, finally, attacked. Either someone wants her to stay away from an investigation, or a demon hunter is targeting her. As Betty begins to fall for Maxwell's mysterious charm, she starts to wonder if her life--and her soul--are worth the risk.

Life is good for Betty "Boo" Boorman. Things are going great with her demon boyfriend Maxwell, and her paranormal investigation team is busier than ever as Halloween approaches. But things go to hell-literally-when Maxwell is banished by a demon hunter. As Betty tries to cope with her grief, another demon enters her life, and he offers her a deal: Betty's soul for Maxwell's rescue. Time is running out for Betty to make a decision, and the ghosts of Savannah, Georgia, aren't making the task any easier. Cryptic messages from the ghost of a little girl seem to be directed at Betty, but are they a warning or a plea for help?
