About the book

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.

Demeter is a fun character, as a ship dropped into multiple impossible situations which, according to her databases, should be fictional. Her vacillation as to whether any of this death is her problem and how can she get the corporation to take her seriously feels very relatable. Steward, the medical AI, is on some ways …”

  • “What. A. Book! I didn't know what to expect from this based on the description, but wow was I floored. Dracula from the perspective of the ship is what I was expecting, and I got that and so very much more! I want to recommend Of Monsters and Mainframes to everyone I've ever met. From it's lovable cast of AI ships, classic monsters, and ethically questionable ship doctor-robots, to it's tightly plotted storyline, it consumed me for days! I don't read that quickly anymore, but every free moment I had was dedicated to reading this book. It's also so fucking funny. Like, seriously. I kept la…”
