A memoir by Serena Williams will be released in 2009 by Grand Central Publishing, which beat out a handful of other publishers bidding for the life story of the No. 1 ranked women's tennis player.

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

Financial terms for the book, currently untitled, were not disclosed, although a publishing official with knowledge of the negotiations said bidding reached at least $1.3 million. The official, citing the confidentiality of the negotiations, declined to be identified.

Williams, 26, has won nine Grand Slam titles and, with sister Venus Williams, won a gold medal in women's doubles at the recent Olympics in Beijing.

Grand Central Publishing is a division of the Hachette Book Group.
