Welcome to the Metrozone—post-apocalyptic London of the future. While 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

Samuil Petrovitch is a survivor.

He survived the nuclear fallout in St. Petersburg and hid in the London Metrozone—the last city in England. He’s lived this long because he’s a man of rules and logic.

For example, getting involved = a bad idea.

But when he stumbles into a kidnapping in progress, he acts without even thinking. Before he can stop himself, he’s saved the daughter of the most dangerous man in London.

And clearly saving the girl = getting involved.

Now, the equation of Petrovitch’s life is looking increasingly complex.

Russian mobsters + Yakuza + something called the New Machine Jihad = one dead Petrovitch.

But Petrovitch has a plan—he always has a plan—he’s just not sure it’s a good one.

THE SIX DEGREES OF PETROVITCH

Michael is an AI of incalculable complexity trapped under the remains of Oshicora tower. Petrovitch will free him one day, he just has to trust Michael will still be sane by the time he does.

Maddy and Petrovitch have trust issues. She’s left him, but Petrovitch is pretty sure she still loves him.

Sonja Oshicora loves Petrovitch too. But she’s playing a complicated game and it’s not clear that she means to save him from what’s coming.

The CIA wants to save the world. Well, just America, but they’ll call it what they like.

The New Machine Jihad is calling. But Petrovitch killed it. Didn’t he?

And the Armageddonists tried to kill pretty much everyone by blowing the world up. Now, they want to do it again.

Once again, all roads lead back to Petrovitch. Everyone wants something from him, but all he wants is to be free…
