A SPY, A MURDER, AND ONE SARCASTIC AI; MYSTERY, ACTION, AND ADVENTURE FROM THE BILLION WORLDS! The Billion Worlds' Greatest Spy Faces His Greatest Challenge At the end of the Tenth Millennium, Sabbath Okada, agent of a nameless branch of Deimos' labyrinthine government comes to the vast city of Ishtar on Venus to investigate the suspicious death of an undercover agent. His companion, Daslakh, is an old and cunning AI with its own self-imposed mission: to act as Okada's conscience. Searching for the truth takes Sabbath and Daslakh to the glittering towers of Ishtar's elite, a brutal combat sport arena, and the unforgiving, wind-lashed face of Mount Maxwell, highest peak on Venus. Along the way they face ruthless Lunar Republic spies, double agents, and sadistic Ishtar police, but Sabbath's greatest challenge comes from Meili Tewa, his deadliest enemy and his only love. Each twist in the case reveals a new layer of deception, another betrayal. Hunted and on the run, with no one he can trust and no help from home--it's time for Sabbath Okada to remind everyone why he's the greatest spy in the Billion Worlds of the Solar System.
