An unstable, poignant, and captivating story for readers of all ages, with the critically acclaimed author of Only Forward.

There are a million stories in the world. Most are perfectly ordinary.

This one… isn’t.

Hannah Green actually thinks her tale is more mundane than most. But she’s going to discover that the shadows in her life have been concealing a world where nothing is as it appears: that there surely is an ancient and secret machine that changes wicked deeds into energy, that some mushrooms can talk – and that her grandfather continues to be friends using the Devil for over a hundred and fifty years, and now they need her help.
