When her best friend Billie is found murdered, eleven-year-old Thera â fearless and forthright â considers it her duty to find the killer. Aided by a Ouija board, Billieâs ghost, and the spirits of four other dead girls, sheâs determined to succeed. The trouble with Thera, though, is that she doesnât always know when to stop â and sometimes thereâs a fine line between doing the right thing and doing something very, very bad indeed. Tense, visceral and thought-provoking, Dead Girls is the new novel from Abigail Tarttelin, the critically acclaimed author of Golden Boy.
