Equations of Life, Samuil Petrovitch

Winner of the 2012 Philip K. Dick Award

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.
