The Expert System's Champion
A novella.
In Adrian Tchaikovsky's The Expert System's Champion, sometimes the ones you hate are the only ones that can save you.
It's been ten years since Handry was wrenched away from his family and friends, forced to wander a world he no longer understood. But with the help of the Ancients, he has cobbled together a life, of sorts, for himself and his fellow outcasts.
Wandering from village to village, welcoming the folk that the townships abandon, fighting the monsters the villagers cannot ― or dare not ― his ever-growing band of misfits has become the stuff of legend, a story told by parents to keep unruly children in line.
But there is something new and dangerous in the world, and the beasts of the land are acting against their nature, destroying the towns they once left in peace.
And for the first time in memory, the Ancients have no wisdom to offer...

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?
