HarperCollins has acquired world rights for what it is calling “the definitive memoir” of one of America’s best-known performers, Cher.

The book was bought by Lynn Grady, senior v-p and publisher of the William Morrow imprint Dey Street Books, from Alan Nevins of Renaissance Literary & Talent Agency. Dey Street editorial director Carrie Thornton will edit the book, which does not yet have a name or pub date. HarperNonFiction will publish the memoir in the U.K. A HC spokesperson said it will decide on a case by case basis whether it will sell rights to the memoir in other countries or publish the book through one of its overseas divisions.

Calling it a “comprehensive, intimate, and revealing memoir” HC said in the book “Cher will tell the story of her journey from high school dropout to becoming one of the best-loved musicians and actresses in history, and winner of a Grammy, an Oscar, an Emmy, and three Golden Globe Awards.” HC promised that the book “will provide fans insight into Cher’s incredible life and career.”

Rising to fame as part of the musical duo Sonny & Cher, Cher has sold over 100 million albums, starred in The Sonny & Cher Comedy Hour, appeared on Broadway and films such as Moonstruck and Mask, and became well-known for her political activism.

“It’s a true thrill and honor to be publishing Cher’s incredible story. She has touched millions of lives with her creative spirit, talent, and heart. Simply put, there is only one Cher, and we can’t wait for her to share her life story—the way she wants to tell it,” said Grady in a statement.
