I don't think you could find a better book for introducing young tennis players to the game. Like all DK books, "How to Play Tennis" by Venus and Serena Williams has lots and lots of big, bright photos. Covered are equipment, the court, warm-up exercises, rules of play, skills--drives, serves, volleys, lobs, smash, drops, positions, etiquette, and strategy, with a glossary and index. The Williams sisters are upbeat and inspiring.
