After being rushed to the hospital, Alice Goodenough finds herself trapped in the worst dream imaginable: a horrible monster is stalking her in the darkness, making its way to the hospital. It will stop at nothing to kill her.

And that’s not the worst of it. All across the city, people are growing more addicted to Castle Cats, a smartphone game created by Grayle Incorporated. And it’s not just a game. The more you play, the more it controls you. Soon, Alice learns that the dwarfs who run Grayle Incorporated are watching her everywhere she goes, using human beings to spy on her.

There must be a confrontation. Sam Grayle and his brothers have to be stopped. And Alice is going to need help.
