City of Salt is the second volume - following Scotlandfuturebog (2002) - in an extraordinary trilogy by Nicholas Kahn and Richard Selesnick.

The Apollo Prophecies depicts, in one extravagantly long tritone panorama, an imagined expedition of 1960s American astronauts who land on the moon and discover a lost mission of Edwardian-era astronauts who greet them as long-awaited gods.
