A fast-paced story centring around Christopher, a boy who lives with mechanicals - sentient robots, essentially.

When Christopher finds out something shocking about his past, he and his friends set off to discover the truth, leading to whirlwind encounters with deranged inventors and power-hungry control freaks.

The language here is rich and absorbing, every line used to develop each character fully and further storylines to such an extent that they could have their own stories. Round Rob was a particular favourite of mine, but Cormier grew on me too as his own backstory was revealed.

Ace stuff.
