Gyata Stormon is an accomplished tennis player, a US and Canadian tennis coach, and three time Canadian senior doubles champion. Her brand new book, "On the Ball: Doubles Tennis Tactics for Recreational Players" began as notes prepared for her students. Eventually she had so many drafts for different level students, and so many pages she still wanted to write, it was time to put it together in one convenient book. Find out more at OntheBallbook.com.
