Before the Wright Brothers opened the era of mechanical, powered flight in 1903, the daytime skies above the Earth were populous and busy. In the Middle Air were hidden the vast sunny cloudland of the Walking-Deck and smaller cloud-isles like Athenaeum and Swan, inhabited by humans since the fall of Troy and by aircats longer than that. In the Lower Air was the gossamer swirl of Springfolden, inhabited for long millennia by the more-or-less intelligent etherine vortices whom men called djinn.
Yet in the Nineteenth Century, volcanic turbulence disintegrated Springfolden and later burnt the Walking-Deck. In 1904, the long-lived Luftmenschen — both humans and aircats — were coming to terms with the wreckage of their comfortable way of life; as the djinn in their own way were as well.
Hendrik Rheinallt, a veteran in his youth of the New Model Army in the English Civil War, was a leader in redefining and redirecting the Luftmensch philosophy of life and action. His aircat friend Arahant and other colleagues and allies were one by one regaining optimism and energy — but so were the hostile djinn.
Then the Sphinx awoke from her caged sleep, and stirred.
Sphinx Daybreak is a standalone science fiction novel (or fantasy novel, if you prefer) which opens the Overflight series.
