In a post-apocalyptic London, a man foils a kidnapping only to find himself in the crosshairs of criminal gangs in this Philip K. Dick Award–winning novel. 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.
