What the fuck is this?

When God is knocked into a coma by a giant box of frosted cornflakes, all Hell literally breaks loose.

In the spiritually over-caffeinated bubble of Boulder, Colorado, a gay atheist barista named Slinger is already struggling with the usual modern crises: existential dread, romantic confusion, and the soul-numbing grind that comes with working in a coffee shop tinged with burnt espresso and spiritual superiority. Then the demons arrive.

What begins as a bizarre supernatural disturbance quickly spirals into a full-scale unraveling of the celestial order. With Heaven in disarray, Hell on the move, and divine leadership temporarily out cold, Slinger must navigate a divine disaster involving ancient forces, bureaucratic dysfunction, and a fight he is wildly unqualified for.

Armed with little more than sarcasm, caffeine, his eccentric coffee shop friends, his possibly straight hippie crush, and a mysterious rabbi who may know more than he’s letting on, Slinger must face his own demons, actual demons, and the terrifying possibility that his abandoned faith might actually matter.

Because if he can’t stop the apocalypse, humanity is going to Hell.

[The Day God Got Amnesia: A Divine Comedy is a 100% human-written book.]

Author

Steven Winkelstein is a writer and product designer originally from New Jersey, now based in Chicago. In a past life, he wrote ten children’s books, including an award-winning title and a Kirkus-recommended book.

These days, he writes fiction that weaponizes absurdity, heart, and humor of questionable morality. The Day God Got Amnesia is his adult comedic fantasy debut.
