Having narrowly survived an encounter with murderous black magic, private investigator Josie P. Cates has settled into the humdrum life of her new profession. But she now faces a challenge far more terrifying: spending a week with her mother. Against all odds, the week proceeds nicely, at least until her friend Arthur disappears at the amusement park run by country music star Tommy Thomas and reality television "celebrity" Ophie Sue Rail. With help ranging from her on-again-off-again boyfriend, her overly-peppy step-sister, and a distant European cousin, Josie must not only rescue Arthur, but unravel the ancient mystery that links Tommy and Ophie Sue.
