The twisted ones
(Book)

"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 packed to the gills with useless garbage. That would be horros enough, but there's more. Mouse stumbles across her step-grandfather's journal, which at first seems to be the ravings of a broken mind. Until she encounters some of the terrifying things he described herself. Alone in the woods with her dog, Mouse has to confront 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" --,Provided by publisher.
