This is not a regular book. You're probably used to books that you read from cover to cover. This isn't one of those books. This book is a lot more interactive than that; this book plays a game with you. You've probably played Hangman before. You think of a word, and the other person tries to guess letters in that word. This book works just like it knows thousands of English nouns, and if you think of one, it will try to guess what it is. It's pretty good at it, too.
