John McEnroe's long-awaited follow-up to his best seller.

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 best seller 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-size 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 percent McEnroe.
