Award-winning author Ursula Vernon, writing as T. Kingfisher, presents a terrifying tale of hidden worlds and monstrous creations...

When Mouse's dad asks her to clean out her dead grandmother's house, she says yes. After all, how bad could it be?

Answer: pretty bad. Grandma was a hoarder, and her house is stuffed with useless rubbish. That would be horrific enough, but there's more-Mouse stumbles across her step-grandfather's journal, which at first seems to be filled with nonsensical rants...until Mouse encounters some of the terrifying things he described for herself.

Alone in the woods with her dog, Mouse finds herself face to face with a series of impossible terrors-because sometimes the things that go bump in the night are real, and they're looking for you. And if she doesn't face them head on, she might not survive to tell the tale.
