In 1816, Gregory Conan Watts's 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.
