The Dark Side — Anthony O'Neill

In this dark and gripping sci-fi noir, an exiled police detective arrives at a lunar penal colony just as a psychotic android begins a murderous odyssey across the far side of the moon.

Purgatory is the lawless moon colony of eccentric billionaire, Fletcher Brass: a mecca for war criminals, murderers, sex fiends, and adventurous tourists. 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 arrives in this wild new frontier, he immediately finds himself investigating a string of ruthless assassinations in which Brass himself -- and his equally ambitious daughter -- are the chief suspects.

Meanwhile, two-thousand kilometers away, an amnesiac 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 -- Black has only one goal in mind: to find Purgatory and conquer it.

Visual, visceral, and tons of fun, The Dark Side fuses hard science with brutal crime and lunar adventure. It's an intense, stylish, and action-packed thriller with a body count to match.
