Two-time Prometheus winner Travis Corcoran has been busy writing fiction -–just not more long-awaited novels in his award-winning Aristillus lunar-revolution series. At least, not yet.

Corcoran is best known for writing The Powers of the Earth and its sequel Causes of Separation, which respectively won the Prometheus Awards for Best Novel in 2018 and 2019. Together, the first two novels in Corcoran’s Aristillus series (named after a lunar crater) tell an integrated and self-contained story centered on an underground lunar colony established by Chinese, Nigerian and American refugees from the economic authoritarianism of Earth’s major nations.
Worlds apart from that future scenario is an alternate history where Rome never fell, and in which printing presses, air travel and electricity were developed centuries earlier than in our own timeline.
