In 1815, in the aftermath of the Napoleonic Wars, two of England's wealthiest lords place a high-stakes wager on whether a popular set of books, which claim that the author has traveled to many unknown corners of the globe, are truth or, more likely, wild fiction. First Light is an epistolary novel, told primarily through the eyes of former aide-de-camp Gregory Conan Watts, describing the journeys of the airship Dame Fortuna and its crew through journals and letters to his beloved fiancée. The first recruit is, necessarily, the airship's owner: war hero, famed genius, and literal knight in steam-powered armor Sir James Coltrane. Persuading him to lend his talents and refitted airship to the venture requires bringing along his sister, his cousin, and the crew that flew with him during the Napoleonic Wars. Only with their aid can they track down a Scottish rifleman, a pair of shady carnies, and a guide with a strong personal investment in the stories. When they set out, the wild places of the world, including the far American West, the Australian interior, darkest Africa, and other destinations are thought to be hostile enough. No one expects the trip to involve a legendary storm - or the Year Without a Summer of 1815-1816. The voyage is further complicated by the human element. Some parties are not at all happy with the post-war political map. Most problematic of all, the crew hired by the other side of the wager seem willing to win by any means necessary. Dawn of Steam: First Light follows these adventurers, as they open up the world. In the process, their journey helps lay the foundations for an age of enlightenment and technology to come.

In 1816, Gregory Conan Watts' chronicle of the adventures begun in Dawn of Steam: First Light continues – as does the Year Without a Summer. The crew of the airship Dame Fortuna travel to four continents and are embroiled in combat on three of them: conflict with New Spain in Britain's American colonies, an ambush in Machu Picchu, and entanglement in the Maori Potato Wars in New Zealand. As they progress through darkened skies, Gregory gradually discovers that nothing at all was as he thought it was. All his assumptions are cast into doubt: what their orders are, which tales of foreign lands are true, and what parts of the social order as he knows it really are natural. Also in doubt is whether they will all survive the experience. Dawn of Steam: Gods of the Sun is an alternate-history, early-era Steampunk epistolary novel.

1817 sees the first signs of recovery from the Year Without a Summer – and the beginning of the end of the journey of the airship Dame Fortuna . The crew first accept a unique offer from the Shogun of Japan, traveling with the Dutch contingent from the island of Dejima into the isolationist nation. From there, their travels will take them through the English colonies in Australia and India, into darkest Africa, and eventually home to England. Along the way, confrontations loom, and both personal secrets and national conspiracies are uncovered. By the time a future queen is born, nothing less than the fate of England and the direction of world events are at stake. Dawn of Rising Suns is an alternate-history, emergent Steampunk epistolary novel, following after Dawn of First Light and Dawn of Gods of the Sun .
