"Emma Clayton tells the story of a future planet Earth that has to deal with cramped, dark, and wet living conditions and an unfair social order due to an animal plague. The characters are realistic, and you want to see the children, who are the story's heroes, defeat the evil and greedy governmental leaders. Be prepared for an interesting twist at the end. The Roar is juvenile science fiction done right, but the concept of death and cruelty is a continuous theme, so this book is better recommended to intermediate students of 4th grade or higher." --Sue Mason, Waucoma Bookstore, Hood River, OR
