This entry in the Influential People series (8 titles) showcases teenage activist Dias, whose enthusiasm for books and reading helped her make a positive difference in others' lives. Brief, accessible chapters and colorful layouts filled with photos and sidebars highlight Dias' background and initiatives, from starting a book drive collecting titles featuring Black-girl protagonists to helping homeless teens living in a shelter to ongoing efforts to promote diverse books, as well as how she advanced her causes. Abundant photos, mainly of Dias, lend visual interest, while short, simply constructed sentences emphasize vocabulary with bold-faced terms, which are defined in the glossary. Also includes instructions for making a grassroots action plan. Elementary-schoolers are sure to be inspired by this profile of a powerful kid not much older than they are.
