Thanks to Gollancz for reprinting another of Christopher Priest's early novels. Priest is an author I knew nothing about until I saw the movie of his 1995 book The Prestige. I've gradually been gathering up his back catalog as they become available.
This edition of Inverted World is published as part of Gollancz's SF Masterworks and has the new "yellow" themed cover.
Inverted World features a strange society of humans who have to keep their city moving on railway tracks. They are trying to keep the city as close to its "optimum" position as they can, however optimum keeps moving. If they fall too far behind then a strange phenomena will destroy the city.
But as with Priest's other works, not everything is as it seems.
I enjoyed the book very much and will be looking forward to reading his others.
