A tense mystery of sabotage and murder with far-reaching repercussions set upon a small space station orbiting Saturn's moon Epimetheus. Roxy took this job to escape her past, specifically to escape her mother. That's hard to do, however, when every feed from Earth is dominated by news from the International Criminal Court in The Hague, which is determined to uncover the truth of what really happened on the fateful day of the Sea of Tranquility Massacre, when humanity's lunar colony was destroyed; the day Roxy's mother murdered the Moon. Things start to get very real when one of her two companions - the mission's commander, Major Nakita Subaru - dies in what appears to be a freak accident, and Roxy suddenly finds herself summoned back to Earth in a remarkably swift manner. Of course, she can't actually begin that return journey until the fast-approaching ship the Cronos arrives. Until then, Roxy is alone with her surviving colleague, Karl, her anxieties, her guilt, and her mounting suspicions... Stephen Deas delivers a gripping slice of high-tension hard SF packed within a deftly crafted novella; epic in scope, precise in its execution.
