Engines of Reason: Elder Race, Book II

The highly anticipated sequel to the Hugo Award-nominated Elder Race, by Arthur C. Clarke Award-winning author Adrian Tchaikovsky.

"[An] epic tale of a land ruled by magic―or the sober record of a world colonized by science...The double vision built into the story works well." ―Wall Street Journal on Elder Race

On a planet where stories govern identity, where science and magic are merely a point of view, a fallen princess, a reluctant wizard, and a precocious child must unravel the past to shape the future.

Betrayal, ancient myths, and a clash of worlds converge in this spellbinding tale of courage, friendship, and self-discovery from one of science fiction's most compelling voices.
