Query: Double Fault

Waintrup, the son of a rabbi, spent fifteen years as a teaching tennis as pro at a New England country club. He tries to tell the story of his life in this book that's a mixed up collection of anecdotes, biography, letters and actual tennis advice. However, he doesn't know if he wants to be a stand-up comedian or a writer as he tells the story. The book fails to come together successfully. He totally missed his shots with this book.
