The Imperial Kassiopei Dynasty and the noble Great Houses hold Service Competitions to pick those best qualified to serve them. Street-smart sixteen-year-old Semmi, fired from her darkness shift job at an industrial warehouse, witnesses a mysterious vigilante known as the Man in the Niktos Cloak and accidentally discovers his impossible secret identity. Powerful nobleman by day-deadly vigilante by night-and the anonymous star of the most popular and hottest adult drama on Atlantean video, Benaten Bisfuri is an irresistible man of many contradictions. To keep his secrets, and keep her quiet, Benaten must hire Semmi to work for him. Desperate for employment, and frightened for her family, she must accept the job. Soon, she's embroiled in Imperial Court politics and a complex plot to save the people who will be left behind-all while competing in the brutal Service Competitions to earn a coveted spot on an ark-ship. She also finds her fate entwined with the uncanny Imperial Princess Arlenari who just might hold the key to everyone's salvation. Before the Sky Rock strikes Earth-bringing about the Great Flood, reprising an Ice Age, and changing the face of the planet forever-Semmi must discover her own abilities to win a place for herself and her loved ones. A place on the Ark. EOS is book one of the series Dawn of the Atlantis Grail.
