Engines of Reason

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

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.
