Equations of Life

Winner of the 2012 Philip K. Dick AwardSamuil 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.
