Preorder Only – Releases September 1, 2026 – Engines of Reason (Elder Race, Book 2)

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.
