Louie "Fitz" Fitzsimmons is getting out of the drugs business. It was never what you might call a career, anyway; he's got problems—strange, violent, vivid hallucinations that have plagued him since he was a kid—and what with one thing and another, this is where he's ended up. So he's been cooking Hollywood gangster Blake Kaplan's books, and putting a little aside for a rainy day—fifteen million, give or take—and he figures it's time to cut and run. Until a vision hits at the worst possible moment, and now he's in hospital and looking at a stretch in County on a possession charge.

Then a Lithuanian goddess of the hunt murders her way into the hospital, and Fitz ends up on the run from a pissed-off angel, and there's new gods – gods of business and the internet – hunting him down, and what started as a bad day gets a whole lot worse.
