What this book is about

Ruth Ware's thriller is structured as a series of letters from Rowan, who is in prison awaiting trial for a child's death, explaining the events at the Heatherbrae House — a smart home with dark secrets. Ware builds her characteristic atmospheric dread; the smart house technology and the isolated Scottish location create effective claustrophobia. The implied violence involving a child is the novel's most disturbing element. For adult readers of psychological thrillers.
