Programmed to undertake the most menial household chores, Charles is loyal, efficient and logical to a fault. That is, until a rather large fault causes him to murder his owner.

Understandably perplexed, Charles finds himself without a master – therefore worthless in a society utterly reliant on artificial labour and services. Fleeing the household, he enters a world he never knew existed. Human hierarchy is disintegrating, and an entire robot ecosystem devoted to its wellbeing is struggling to find a purpose.

Charles must face new challenges, illogical tasks and a cast of irrational characters. He’s about to discover that sometimes all it takes is a nudge to overcome the limits of your programming. But can he help fix the world, or is it too badly broken?
