Welcome to the Metrozone - post-apocalyptic London of the future. Whilst the rest of Britain has devolved to anarchy, the M25 cordon protects a decaying city filled with homeless refugees, street gangs, exiled yakuza, crooked cops and mad cults. And something else; something new and dangerous.

Enter Samuil Petrovitch: a Russian émigré with a smart mouth, a dodgy heart and a dodgier past. He's brilliant, friendless, cocky and - armed only with a genius-level intellect, prototype cyberware and a prodigious vocabulary of Russian swear words - might just be most unlikely champion a city has ever had.

Welcome to the future. Mind the gap.

This omnibus edition contains Equations of Life, Theories of Flight and Degrees of Freedom.
