This nonfiction biography is one of the "Fact Finder" series designated for readers in grades three through five. It begins with an account of Muhammad Ali's 1974 boxing match against George Foreman. Following are several chapters describing his childhood and his beginning experiences in learning to box. There are several chapters devoted to his years as a professional boxer that include the reason he changed his name, his problems that occurred when he refused to sign up for the draft, and his return to boxing. The last portion of the book discusses his life since his illness and concludes with a photograph and text about his lighting the flame to open the Olympic games in 1996. Photographs throughout the book are in both black-and-white and color. On some pages, there are quotations in separate boxes from Ali, his trainer, and former President Bill Clinton. Several boxes state facts about Ali and his profession. A table of contents, a glossary, and an index are included. A "Fast Facts" one-page biography, a two-page time line, a listing of Internet sites, and a short list of related books are given at the conclusion. This biography is a good mixture of text and photographs. It is written in a style that is interesting and easy to understand, and would be helpful as a resource for biographical research.
