A third mishap in as many months has nearly befallen the tourist trade on Mars. Enna Dacourt, however, senses it was no accident. Only her quick thinking prevented further depletion of public confidence, which threatens to hand the initiative to competitor Artemis Outland, the Moon tourism specialist. The lead data architect on the Mars Advance program is found dead in a hotel room, apparently from a heart attack. Then the Mars Advance team find that a vital data backup drive is missing. Is this all the work of pacifist anti-colonisation activists OnePlanet, or are other forces at work? Can Enna, unexpectedly pregnant but unwilling to compromise her work ethic, unpick the web of conspirators who threaten not only the organisation she holds dear, but ultimately the lives of her new family?
