In true pulp fiction form, HAWTHORNE: Chronicles of the Brass Hand is the story of young Edgar J. Hawthorne as he sets out on a journey to the Royal Observatory at the Cape of Good Hope, South Africa, to investigate the Great Moon Hoax of 1835 after reading an article in the Edinburgh Journal of Science, submitted by none other than close family friend John Herschel.
Traveling with the Royal Air Brigade on the Stratos, England's newest and most advanced airship, pride of the British fleet, Edgar and the crew, caught unaware, are attacked in the early hours of dawn by a flotilla of marauding airships. Outnumbered and through a series of seemingly unforeseen malfunctions the Stratos is forced down into the deep jungles of Africa.
With the Stratos crippled and in need of repair Edgar along with the first officer and a portion of the crew set out to locate provisions. What Edgar discovers in the jungle, however, convinces him there are other forces involved in the downing of the Stratos. In the attempt to discover the truth behind the attack Edgar unearths a secret so colossal and far-reaching that it will change his life forever.
Finding himself entangled in a conflict which has raged for centuries Edgar is thrust into a world that only a handful are aware of and with the aide of a mysterious girl and an ally who is not whom he appears to be Edgar must do the impossible, save mankind from extinction.
