If you hear it, it’s too late. Can two sisters save us all?
Two sisters have always stood together. Now, they’re the only ones left.
In the shadow of Mount Hood, sixteen-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 . . .
