Alain Robert spent his youth on the unforgiving cliffs of southern France, climbing with his bare hands, with no ropes for protection. In 1982 he fell head-first onto solid rock, suffering a five-day coma and multiple fractures. He was told he would never climb again. But this didn't stop him. In 1994, he climbed his first skyscraper, in Chicago ? and the 'Human Spider' was born. Warning: this gripping autobiography may induce serious vertigo.
