Once an apex predator that ubiquitously prowled North America, the wild, powerful, and majestic gray wolf has faced much adversity at the hands of mankind. In this comprehensive tome of wolf-related information, readers gain insight into a range of topics covered in 2-page increments, including details of habitat, behavior, scientific research, threats to survival, and return from the brink of extinction. Unfamiliar, content-based terms are bolded and further described in an index at the back of this 48-page nonfiction book aimed at middle level readers. Rich in text, the pages are divided into colored boxes that highlight different elements of information, from fun facts to picture captions to explanatory paragraphs similar to simple encyclopedia entries. A wealth of images—photographs, drawings, diagrams, and maps—dons each spread and provides an intimate glimpse into the nature of these regal, cunning canines. With its sound factual content and vivid visual elements, this reference book is ideal for a wide range of ages, learner types, and reading levels, particularly when coupled with the support of an advanced or adult reader.
