"Fans of Murderbot will love this quirky sci-fi romp." --USA Today


Spaceships aren't programmed to seek revenge--but for Dracula, Demeter will make an exception.

Demeter just wants to do her job: shuttling humans between Earth and Alpha Centauri. Unfortunately, her passengers keep dying--and not from equipment failures, as her AI medical system, Steward, would have her believe. These are paranormal murders, and they began when one nasty, ancient vampire decided to board Demeter and kill all her humans.

To keep from getting decommissioned, Demeter must join forces with her own team of monsters: A werewolf. An engineer built from the dead. A pharaoh with otherworldly powers. A vampire with a grudge. A fleet of cheerful spider drones. Together, this motley crew will face down the ultimate evil--Dracula.

The queer love child of pulp horror and ​classic ​sci-fi, Of Monsters and ​Mainframes ​is a dazzling, heartfelt odyssey that probes what it means to be one of society's monsters--and explores the many types of friendship that make us human.

What a charming little book. I have some quibbles, but you know what? Sometimes the quibbles don't matter. This is a book about spaceships and monsters, written with such verve and brio that I don't care about the quibbles. The characters are fun, the story is fun, the premise is a hoot. This book is just a really good time, and I love it for that.

What's not to love about Dracula in space with werewolves and Frankenstein (amongst so many more classic ghouls and monsters)! The anxiety the spaceship communicates coupled with the absolute snobbery of the Med-unit is both hilarious and relatable. It's a rollicking feel-good adventure.
