A #1 New York Times Bestselling Author
Two sisters have always stood together. Now, they're the only ones left.
In the shadow of Mount Hood, 16-year-old Tennant is checking rabbit traps with her eight-year-old sister Sophie when the girls are suddenly overcome by a strange vibration rising out of the forest, building in intensity until it sounds like a deafening crescendo of screams. From out of nowhere, their father sweeps them up and drops them through a trapdoor into a storm cellar. But the sound only gets worse. If you hear it, it's too late. Can these two sisters save us all?
