In the late summer of 1997, Luna spent a week house-sitting at her uncle's property on Ponderosa Lane, a dead-end road outside the small town of Crestwood, Tennessee. The house was surrounded by woods and a dried-up creek bed that locals called the Hollow. But on the third night, she started hearing the scratching. Not from the walls or the roof — from under the floorboards in the spare bedroom. And when she pried up a section of the subfloor, she found something that should not have been there: a child's handprint, fossilized into the concrete foundation. The next morning, she asked the old man who lived next door about the house. He looked at her with a strange pity and said, 'You didn't find the hollow, did you?' This is a story about the things that get sealed away — and the difference between a house that is empty and a house that is waiting.
