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.
