Gr 6 Up—These thorough biographies run from each subject's birth to the present day, sharing their unique paths to greatness. Some of the books are slightly more robust, if only because the athletes have had longer to establish their careers. For soccer star Kylian Mbappe and football quarterback Patrick Mahomes, the authors focus heavily on their significant games. Serena Williams, LeBron James, and José Altuve all have stellar careers and philanthropic hearts, with Williams traveling often to Africa, James creating his I Promise school in Akron, and Altuve's Astros helping Habitat for Humanity after Houston's devastating hurricane. Sidebars add fascinating tidbits to the life stories, like how "Tiger-proofing" Masters courses by making them longer actually gave Woods even more of an advantage over his peers. Source notes support the text with ample citations in the back matter. VERDICT A highly readable and inspirational series.
