The only work of sci-fi from an author normally associated with more sedentary works on transport; this Lost Race tale set in the Yukon Territory, 'within a caldera heated by volcanic action, a technologically advanced but priest-ridden civilization of "white Indians", originally from ancient Egypt, uses its helicopter-like airships and strange Weapons to attempt to protect its gold from the outer world.' (The Encyclopedia of Science Fiction).
