A hilarious fantasy novel perfect for fans of Good Omens, The Dresden Files, and Terry Pratchett. If you like your eldritch horrors with a side of snark and a lot of heart, welcome to the holidays in Chicago.

Infinite cosmic power. Itty-bitty living space.

To the universe, he is a Class Omega entity of undefined chaos, capable of rewriting reality and staring down elder gods. To Detective Emily Chen, he is Mr. Whiskers: a stray black cat who appeared at a crime scene, eats too much Fancy Feast, and refuses to stay off the furniture.

It is 1982 in Chicago, and the cracks in the world are starting to show. A cult obsessed with an ancient serpent is stealing artifacts, bodies are vanishing from the morgue, and a comet is hurtling toward Earth with an appetite for destruction.

Trapped in a feline body, stripped of his powers, and forced to rely on a skepticism-prone detective and a teenage bellhop with a baseball bat, the universe's most chaotic entity has until Christmas Day to save the world.

He just has to finish his nap first.
