I have something for you. When Quinn Cruz receives that cryptic text message from her older sister Nora, she doesn’t think much of it. They haven’t seen each other in nearly a year and thanks to Nora’s fierce aloofness, their relationship consists mostly of infrequent phone calls and an occasional email or text. But when a haunted Nora shows up at the lake near Quinn's house just hours later, a chain reaction is set into motion that will change both of their lives forever.
