Bonatti published his second autobiography, Montagne di una vita in 1998 with Marshall's involvement who also translated the book as Mountains of my life in 2001. It put forward his oxygen theory along with the photographic evidence and suggested the idea that Desio had believed the worst of Bonatti by accepting he had tried for a unilateral attempt on the summit, and treating him unfairly in the book while at the same time giving an account of a well organised expedition. Then Bonatti published K2, la verità: storia di un caso in 2003 which included articles from many experts and journalists supporting Bonatti's case.
