Engines of Reason
Visit a world where sorcery intertwines with science by multiple Hugo nominee Adrian Tchaikovsky in this highly-anticipated sequel to his hugely popular Elder Race.
On a planet where stories govern identity, where science and magic are a merely 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 the clash of worlds converge in this spellbinding tale of courage, friendship, and self-discovery.
A profound exploration of identity, memory, and discovery from one of science fiction’s most compelling voices.

Adrian Tchaikovsky
In the realm of speculative fiction, where the boundaries between science and imagination blur, Adrian Tchaikovsky writes with the precision of a biologist and the curiosity of a philosopher. Known for weaving evolutionary theory into alien worlds and giving sentience to the most unexpected of creatures, he crafts stories that challenge not just what it means to be human—but what it means to be alive.
Tchaikovsky’s breakout novel, Children of Time, didn’t just introduce readers to a distant planet populated by hyper-intelligent spiders—it redefined what readers expect from space opera. Bold, cerebral, and emotionally resonant, the book went on to win the Arthur C. Clarke Award, with its sequel Children of Ruin deepening the saga’s exploration of consciousness, cooperation, and survival. In 2023, the Children of Time series earned the Hugo Award for Best Series, a fitting recognition for stories that dare to look evolution in the eye and ask: what if?
