It's not every farmer who can claim to have been killed by a whale falling from the sky. Fewer still can say they were brought back to life. But David Eno can.

Impossible? Not when you're in purgatory. Of course, no one else calls it that. Not even David's parents. They believe they're colonists on an alien planet. But David knows, and that's why he's made it his mission to find a way out.

It won't be easy; purgatory is teeming with demons. Fortunately, David has a pair of good-luck charms up his sleeve: a canine companion that's more grizzly bear than dog, and a rifle that never runs out of bullets. But as he soon discovers, sometimes the worst demons are the ones dwelling in our past, and it's only after revisiting a childhood tragedy that David can truly begin the difficult task of setting himself free.
