Book excerpt: Welcome to West Berlin, 1967. Undercover agent Peter Urbach is tasked with infiltrating a group of radical students whose anti-consumerist message is not without propaganda value on both sides of the Wall. Soon, high-minded political activism will move to the terrorism of the Red Army Faction. In 1989, the Wall is coming down and Urbach is breaking cover to track down Peter Green, the genius behind British blues rock band Fleetwood Mac. There's unfinished business to resolve after their chance encounter twenty years earlier at a party in Germany. What exactly did Peter Green walk into that day? "[An] intriguing period thriller. . . Resonances with the Occupy Wall Street Movement make this novel's themes timely."-Publishers Weekly
