The Dark Side

In this gripping sci-fi noir for fans of The Martian and Quentin Tarantino, when an anarchic android begins wreaking havoc on a moon-based penal colony and bodies start turning up, an exiled detective must decide who he can trust in a city of criminals.

Never bang your head against a wall. Bang someone else’s.

Purgatory is the lawless moon colony of eccentric billionaire, Fletcher Brass and mecca for war criminals, murderers, and curious tourists alike. You can’t find better drugs, cheaper plastic surgery, or a more ominous travel advisory anywhere in the universe. But trouble is brewing in Brass’s black-market heaven. When an exiled cop comes to enact law and order in this wild new frontier, he finds himself the lead investigator in a series of high-profile murders that puts him toe to toe with the city’s charismatic founder and his equally ambitious daughter.

Meanwhile, 2000 km away a memory-wiped android, Leonardo Black rampages across the lunar surface. Programmed with only the notorious “Brass Code”—a compendium of corporate laws that would make Ayn Rand blush—he journeys across the dark side of the moon with only one goal in mind: find Purgatory and conquer it.
