Gr 9 Up—So often books about spiders and butterflies or snakes and reptiles are written for a younger audience. This series is the exception—high school students interested in the natural world and willing to engage with densely packed volumes are the intended audience. Each title provides a comprehensive exploration of the subject. Butterflies & Moths, for example, begins with a general introduction and then covers anatomy, flight and migration, wing patterns and colors, various species, the life cycle, and some of the environmental challenges these creatures face. A variety of differently sized bold photographs break up the text; some are even a full page. An extensive index, Internet resources, and educational videos available through QR codes are included in the back matter. VERDICT An information-rich resource for studious teens.
