Way back in 1988 I wrote my first novel, Roofworld, about disaffected youths living in rooftop communities. It’s taken 22 years, but it looks like that future has finally arrived. This is Dmitri Yermakov, 18. He’s part of a youth subculture that has taken shape in Moscow. Its adherents are called Roofers, and they gain access to Moscow’s buildings not for criminal intent, but to climb the roofs.
