Mars is supposed to be dead.… Bizarre quakes are rumbling over the long-dormant tectonic plates of the planet, disrupting its trillion-dollar mining operations and driving scientists past the edges of theory and reason. However, when rocks shake off their ancient dust and begin to roll—seemingly of their own volition—carving canals as they converge to form a towering structure amid the ruddy terrain, Lt. Jain and her JSC team realize that their routine geological survey of a Martian cave system is anything but. The only clues they have stem from the emissions of a mysterious blue radiation, and a 300-year-old journal that is writing itself. Lt. Thomas Weatherby of His Majesty’s Royal Navy is an honest 18th-century man of modest beginnings, doing his part for King and Country aboard the HMS Daedalus, a frigate sailing the high seas between continents…and the immense Void between the Known Worlds. With the aid of his fierce captain, a drug-addled alchemist, and a servant girl with a remarkable past, Weatherby must track a great and powerful mystic, who has embarked upon a sinister quest to upset the balance of the planets—the consequences of which may reach far beyond the Solar System, threatening the very fabric of space itself.
