The Twisted Ones

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 the diary of her late step-grandfather, Frederick Cotgrave, who had been obsessed with something called "the twisted ones" before he died. What starts as an unsettling family mystery escalates into a full-blown nightmare when the creatures begin to invade reality and hunt those around them.
