If There Be Thorns (Dollanganger 3)

Christopher and Cathy have made a loving home for their handsome and talented teenager Jory, their imaginative nine-year-old Bart, and a sweet baby daughter. Then an elderly woman and her strange butler move in next door. The Old Woman in Black watches from her window, lures lonely Bart inside with cookies and ice cream, and asks him to call her “grandmother.” Slowly Bart transforms, each visit pushing him closer to the edge of madness and violence, while his anguished parents can only watch. For Cathy and Chris, the horrors of the past have come home…and everything they love may soon be torn from them.
