How would you feel if you encountered a 12 ft. tall bird? Or a 6 ft. tall, 10 ft. long ox? As strange and potentially alarming as they might sound, these and other giant creatures ruled their ecosystems until humans hastened their extinction. In his book, Campbell describe the origins, history, role, and extinction of thirteen “giants” of nature. Each account is incredibly interesting, but detailed and written with a sophisticated, scientific style that may not appeal to all of the teen readers to whom it is marketed. Despite a few half-hearted and awkward references to social media, and an occasional break in tone for an attempt at teen-speak, the book reads like a scientific article. So while it won’t attract a broad teen audience, it is fantastic for high schoolers and adults who are interested in the subject matter and looking for a well-researched, thorough narrative about the evolution, impact, and decline of each species–as well as a glimpse into the future of possible back-breeding to restore giants into the ecosystem.
An engaging read which I recommend to older teens and adults who are interested in biology and/or history.
