The Curve of The Earth (Metrozone, 5)

Welcome to the Metrozone - post-apocalyptic London of the Future, full of homeless refugees, street gangs, crooked cops and mad cults. Enter Samuil Petrovitch: a Russian émigré with a smart mouth, a dodgy heart and a dodgier past. He's brilliant, selfish, cocky and might just be most unlikely champion a city has ever had. Armed with a genius-level intellect, extensive cybernetic replacements, a built-in AI with god-like capabilities and a plethora of Russian swearwords - he's saved this city from ruin more than once. He's also made a few enemies in the process - Reconstruction America being one of them. So when his adopted daughter Lucy goes missing, he's got a clue who's responsible. And there's no way he can let them get away with it.
