About this book

Book Summary

A dark science fiction debut examining agency and sacrifice through one man's desperate attempt to reach home after he murders his tyrannical employer.

Verden Dotnet made an easy living mixing drinks for the creator of all sentient tech in the galaxy—until he decided to kill the creator. Now this man is dead, really dead, no cloud back-ups, and V-Dot is on the run, carrying a galaxy-shattering secret in his pocket. When he misses the last ship back to Ganymede, he convinces an old, outdated but still sentient ship, TR-8901, to give him a lift.

But TR suspects that something is up—it is hearing rumours about his creator's death, and the man who fled the scene. But TR is a dutiful ship, and will carry out its duties until proven otherwise…

Media Reviews

"With meticulous technical detail, abundant local color on various space stations and Martian locales, and sharply drawn characters, this sprawling novel will appeal to both hard sci-fi fans and readers looking for thought-provoking insights into an all too possible future where humans and AI must find an effective symbiosis if both are to survive." —Publishers Weekly (starred review)

"Sci-fi as dark as the space between the stars, with a noir tint to the station hopping intrigue and a twist of black humour. It is a propulsive and stylish thriller following a murderous mixologist and your new favourite suicidal spaceship, packed with high concept questions and fantastic set-pieces." —Ian Green, Arthur C. Clarke Award-nominated author of Extremophile
