Animal-rescue stories are always popular; this book enhances the topic by delving into how prosthetics dramatically improved the lives of five animals. The gravely injured subjects -- a Kemp's ridley sea turtle, an Asian elephant, a German shepherd, a goose, and a pig -- were rehabilitated thanks to the compassion, perseverance, and collaboration of teams of rescuers and researchers. Each affecting story includes captioned photos of the animal subjects and their human caregivers. A related activity follows each story, helping readers better understand animal body mechanics and scientists' creative problem-solving methods. A glossary, selected bibliography, related organizations, and index are appended.

Gutiérrez profiles five "bionic beasts," animals whose prosthetic body parts help them to function.Matter-of-factly, she introduces three animals that each have only three legs: Lola, a Kemp's ridley sea turtle from Texas; Mosha, an Asian elephant from Myanmar; and Cassidy, a German shepherd from New York. Pirate, a Berkshire-Tamworth pig from Vancouver Island, has a deformed leg; Vitória, a greylag goose from Brazil, lacks a beak. The animals struggled to move or eat until veterinarians, designers, and doctors teamed up to create innovative prostheses and orthoses. The prostheses' complex design processes are clearly described. Sidebars provide animal facts and highlight various rescue organizations; the book's bright yellow and green color scheme complements the accompanying color photos. Though technology is the primary focus, the author acknowledges political and environmental issues in the animals' habitats, such as ongoing civil wars in Myanmar and oceans cluttered with plastic waste. Activities follow each profile. Some attempt to mimic the teams' challenges by constructing mock prostheses from household items and exploring strengths and weaknesses of various designs. Others edge problematically into disability simulation, such as imitating Pirate's walk "to understand how Pirate feels" without his orthosis; though well-meaning, the exercise risks encouraging pity for similarly disabled humans and feels incongruous with other, inclusive instructions: "if you are able"; "or observe a friend."

Gr 4-8 This title discusses animals that have been injured and given prostheses to improve their lives. Gutiérrez highlights five different animals, educates readers on each particular species, and explains how they became injured. The narratives also detail how the prostheses were made for each animal, as making a flipper for an injured turtle is a different process than constructing a foreleg for an elephant. Readers interested in biomedical technology will appreciate the instructions for building small-scale prosthetic models using household items. VERDICT Examining environmentalism, animal rescue, and technological possibility, this science-filled book for upper-elementary to middle school readers entertains in many forms.
