The Expert System's Brother

Award-winning master of science fiction Adrian Tchaikovsky brings readers a mind-expanding adventure in The Expert System’s Brother.

After an unfortunate accident, Handry is excommunicated from his village. He's forced to wander a world he doesn’t understand, searching for meaning. But can an unlikely saviour provide the answers to the questions he barely comprehends?

Hendry soon finds himself traveling outlying settlements, guided by the Ancestors - who first settled the world from a distant planet. And as Hendry gathers an entourage of outcasts, he battles monsters and may even become a legend himself.

This wanderer also discovers that the life he thought he knew is far stranger than he could even possibly imagine.
