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.

Before his victory at the Nile. Before his scandalous personal life made headlines. Before he crushed the French and Spanish fleets at Trafalgar. Before he died a martyr. Horatio Nelson, England's greatest naval hero, assumed his first command, the 12-gun brig HMS Badger, at the tender age of 20. History tells us his first voyages as captain were unremarkable. Yet in the Known Worlds, where sailing ships ply the Void and the mystic science of alchemy works wonders, Nelson's first command goes quite differently. With his brashness and emotions untempered by experience, Nelson's rash actions as captain of the Badger threaten his heroic destiny. The Gravity of the Affair is a novella set in the Known Worlds of The Daedalus Incident, with events that tie into the novel (though both works may be enjoyed independently of one another).

Two dimensions collided on the rust-red deserts of Mars—and are destined to become entangled once more in this sequel to the critically acclaimed The Daedalus Incident. Lieutenant Commander Shaila Jain has been given the assignment of her dreams: the first manned mission to Saturn. But there’s competition and complications when she arrives aboard the survey ship Armstrong. The Chinese are vying for control of the critical moon Titan, and the moon Enceladus may harbor secrets deep under its icy crust. And back on Earth, Project DAEDALUS now seeks to defend against other dimensional incursions. But there are other players interested in opening the door between worlds . . . and they’re getting impatient. For Thomas Weatherby, it’s been nineteen years since he was second lieutenant aboard HMS Daedalus. Now captain of the seventy-four-gun Fortitude, Weatherby helps destroy the French fleet at the Nile and must chase an escaped French ship from Egypt to Saturn, home of the enigmatic and increasingly unstable aliens who call themselves the Xan. Meanwhile, in Egypt, alchemist Andrew Finch has ingratiated himself with Napoleon’s forces . . . and finds the true, horrible reason why the French invaded Egypt in the first place. The thrilling follow-up to The Daedalus Incident, The Enceladus Crisis continues Martinez’s Daedalus series with a combination of mystery, intrigue, and high adventure spanning two amazing dimensions.

The last chapter of the dimension-spanning Daedalus series brings the 19th and 22nd centuries together for an explosive finale in the jungles of Venus! In the year 2135, dangerous alien life forms freed in the destruction of Saturn's moon Enceladus are making their way towards Earth. A task force spearheaded by Lt. Cmdr. Shaila Jain is scrambling to beat them there while simultaneously trying to save crewmember Stephane Durand, who was infected during the mission to Saturn and is now controlled by a form of life intent on reopening a transdimensional rift and destroying the human race. But Jain doesn’t realize that the possessed Stephane has bigger plans, beaming critical data to other conspirators suspiciously heading not for Earth, but for Venus… In 1809—a Napoleonic era far different from our own—the French have occupied England with their Corps Eternélle, undead soldiers risen through the darkest Alchemy. Only the actions of Lord Admiral Thomas Weatherby and the Royal Navy have kept the French contained to Earth. But the machinations of old enemies point to a bold and daring gambit: an ancient weapon, presumed lost in the jungles of Venus. Now, Weatherby must choose whether to stay and fight to retake his homeland or pursue the French to the green planet. And Shaila must decide if it’s possible to save the man she loves, or if he must be sacrificed for the good of two dimensions. In the dark, alien jungles of Venus, humanity's fate in both dimensions hangs in the balance—forcing past and present to once again join forces against an ancient terror.
