Unlike the handful of other sports trivia books aimed at middle-grade readers -- each of which focuses on one sport -- this book has broad appeal, with 19 different sports included. Not only does it include tidbits from college-level competition along with professional-level sports, but it achieves a balance between men's and women's sports unusual in this subject. All kinds of factoids are found in the pages of this highly entertaining book. Examples of questions answered are: How was waterskiing invented?
