Serena Williams will write about her life on and off the tennis court in an upcoming memoir for Grand Central Publishing, which beat out several other publishers in a fierce bidding war for her story.

Financial terms of the deal weren't disclosed, but an official with knowledge of the transaction said bidding reached at least 1.3 million, according to the Associated Press.       

The 26-year-old has won nine Grand Slam titles and a gold medal in women's doubles at the recent Beijing Olympics with her sister Venus.

Grand Central editor Karen Kosztolnyik, said "Serena Williams is one of the world's most remarkable athletes."

"We've watched her rise to No. 1 despite physical and emotional setbacks, and her hard work and determination have inspired legions of fans young and old. Serena will give her memoir a strong motivational slant."
