Extreme Sports by Michael Dean is about the world of exciting and dangerous sports. These sports range from BASE jumping to cave diving. He splits these into sections about extreme air, ground, and water sports. This Penguin Reader starts with a questionnaire to determine if the reader would be a good extreme sport participant. From there, we get an A-Z of Extreme Sports, where readers can decide which sports they may or may not be willing to try. Following this is some background information and the history about the most dangerous extreme sport, BASE jumping. It is thought that about one person a year dies from it. We learn about the hang gliding world champion, Bill Moyes and the instructor, Michael Costello, who gave his life to save his student's. We read about Bren Jones's near-death experience as he did aerial ballet. And the author tells of his own experiences doing cave diving. The author gives a lot of information about when and where these sports started, who did them and what dangers are involved. For example, in 1965 while watching his daughter sliding on wood on the ice, Sherman Poppen came up with the invention that we now call a snowboard. So without his daughter, Wendy, we would not have this very trendy sport today. As there are Olympic Games for athletes around the world, there are now X games, which started in 1995. They take place twice a year in the United States, one in summer, the other in winter. Since 1997, they have been held in Asia, Australia, and Europe, and there are even X games for kids. It is the happening thing for extreme sports lovers around the world. Everyone has it in them to learn. Take it from Michael Bane (he could not swim, and was afraid of heights), who swam from Alcatraz to San Francisco in water that is not only freezing cold, but is shark infested! The book then ends with ?What do you know now about Extreme Sports?" testing the readers to see if they were really taking it all in.
