"Tooth and Nail" is a novel that teaches vocabulary for the Scholastic Aptitude Test (SAT) in context. Rather than presenting lists of vocabulary words to memorize, the mystery novel presents some 1,200 words, which have appeared in past SATs, in context. The story, about going off to college, features a literacy treasure hunt involving rare books and manuscripts. SAT words are printed in boldface. A comprehensive glossary at the back of the book provides readily accessible definitions as well as references to pages where each word appears. SAT-style exercises are also presented, and the preface provides some general test-taking advice. (SLD)
