About the Book

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.

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.

Teioch the Terrible: A Serenade of Stars

A young obsidian dragon, exiled, nursing a wound he has definitely, completely gotten over. He intends to conquer the known world — less for the power than for how the ballads will sound. He is also, to everyone's surprise including his own, an excellent engineer.

Meanwhile, one by one, the stars are going out. He hasn't noticed. Dragons rarely look up.

About Joshua

Joshua D. Koester lives in the Midwest with his wife, two kids, her parents, and a pair of insane dogs — a collie named Duke who is a gentleman and a scholar, and a golden retriever named Mad Max Rockastansky who is a bloody idiot and a menace to society. We still love him.

When he isn't writing, he's making video games, illustrating, programming, creating data pipelines, or smashing large tires with a sledgehammer — sometimes all in the same afternoon. He likes long walks off short piers, carbs, and 80's movies. Mr. Whiskers: Lord of the Void is his latest novel.
