From the five-time Grand Slam winner Maria Sharapova, the candid, captivating story of her rise to tennis stardom

In the middle of the night, a father and his daughter step off a Greyhound bus in Florida and head straight to the Nick Bollettieri Tennis Academy. They ring the bell, though no one is expecting them and they don't speak English. The two have arrived from Russia with only seven hundred dollars and the conviction that this six-year-old will be the next tennis star. Amazingly, they are right.

Young Maria Sharapova went on to win Wimbledon at just seventeen years old, in an astonishing upset against the reigning champion Serena Williams--the match that kicked off their legendary rivalry and placed Sharapova on the international stage. At eighteen, she reached the number one WTA ranking for the first time, and has held that ranking many times since. In this gripping autobiography, the five-time Grand Slam winner recounts the story of her phenomenal rise to success, narrated with the same no-holds-barred, fiercely provocative attitude that characterizes her tennis game. Full of thrilling, insightful episodes from her beginnings in Siberia, from career-defining games, and from her recent fight to get back on the court, Unstoppable is an inspiring tale of persistence, pulsing with fearlessness and candor. Sharapova's is an utterly unforgettable story.
