One mother’s love may be all that stands between her family, an enigmatic presence–and madness.

After years of city life, Orla and Shaw Bennett are ready for the quiet of New York’s Adirondack mountains. Settling into the perfect farmhouse with their two children, they are both charmed and unsettled by the expanse of their land, the privacy of their individual bedrooms, and the isolation of life a mile from any neighbor. But none of the Bennetts could expect what lies waiting for them in the woods. When something begins to call to the family–from under the earth, beneath the trees, and within their minds–Orla realizes she might be the only one who can save them … if she can find out what this force wants before it’s too late.
