Draft:The Olympian Affair

The Olympian Affair is a 2023 steampunk fantasy novel by Jim Butcher. It is the second novel of the Cinder Spires series, and the sequel to the first novel, The Aeronaut's Windlass.

Setting
The novel takes place on a world in which humans live in "spires," huge cylindrical arcologies 10,000 feet (3,000 meters) tall and 2 miles (3.2 km) across. Back on earth, their world is a place of horrors, full of dangerous beasts that occasionally make their way into the spires.

The technology and culture seem to be similar to 18th century Europe. Technology based around vat-grown crystals allows citizens to create airships that sail the skies, similar to a Golden Age of Sail vessel. These same crystals can be used to generate electricity and power energy-based weapons.

Spire Olympia is the primary setting, though portions of the book also take place on Spire Albion and Spire Aurora.
