He is one of the most controversial and beloved athletes in history, a tennis legend and a volcanic, mesmerizing presence. But after reaching the top of his game - what came next? Fifteen years after his international number-one bestseller You Cannot Be Serious, John McEnroe is back and ready to talk. Now the undisputed elder statesman of tennis, McEnroe has won over his critics as a brilliant commentator at the US Open, Wimbledon, and other Grand Slam tournaments - with outspoken views on the modern game, its top players, and the world of 21st century sport and celebrity. Who are the game's winners and losers? What's it like playing guitar onstage with the Rolling Stones, hitting balls with today's greats, confronting his former on-court nemeses, getting scammed by an international art dealer, and raising a big family while balancing McEnroe-sized expectations? In But Seriously , John McEnroe confronts his demons and reveals his struggle to reinvent himself from champion and tennis legend to father, broadcaster, and author. The result is a richly personal account, blending anecdote and reflection with razor sharp and brutally honest opinions, all in McEnroe's signature style. This is the sports book of the year: wildly entertaining, very funny, surprisingly touching, and 100% McEnroe.
