Dark Places is about Libby Day, a woman in her late twenties whose family was brutally murdered when she was only seven. Her older brother, Ben, then only fifteen, is serving a life sentence for the crime, based largely on Libby’s testimony. Libby’s life is filled with anxiety and depression and loneliness—she has nothing left, having driven away her remaining extended family and having used up almost all of the money she received from well-meaning strangers who heard of her story. Things are shaken up when Libby gets contacted by a member of “the Kill Club,” a group that meets to discuss and solve old mysteries. They think that her brother, Ben, is innocent—and they’re willing to pay Libby a lot of money to help them figure out what really happened on that night.
