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?
