Ghost Girl DeeDee Olsen Blanchard is back with another supernatural case to solve. Now an adult and Child Psychologist, she practices medicine in her hometown of Pahokee, Florida. New patient, seven-year-old Ethan Portman, is brought to DeeDee by his mother for treatment of what she believes is a dissociative disorder, telling DeeDee that he has always been a happy and loving child but has suddenly become despondent, refuses to eat, and no longer plays with his toys. Upon her assessment of, and conversation with Ethan, DeeDee discovers that his condition isn't medically related. Ethan is being haunted by the dead twin brother that he never knew existed who is attempting to persuade him to join him so that they can be together forever. To Dee Dee's shock and dismay, she understands that the only way her patient can be with his dead brother is for him to die as well. Determined to learn about the life and history of Nathan Banks, the deceased twin, DeeDee must go deep into the Florida Everglades to solve his murder. What she finds in her quest for the truth is gruesome and heartbreaking. Nathan's ghost leads DeeDee and her husband, David, to Earl and Maylene Tibbetts, an ill-bred, illiterate, backwoods degenerate couple with a long history of abducting and murdering children across the state of Florida. The Tibbetts' farm hides many dark and disturbing secrets, and it's up to DeeDee to expose Earl and Maylene and the multiple crimes they've committed. Putting her own life at risk, she sets out to not only free the souls of the children trapped on the farm, but also to rescue the five living ones who remain there before the Tibbetts kill them, too.
