A biography of Sarah Palin written for 9- to 12- year olds is slated to hit shelves this September, the AP reports.

The unauthorized book is one in a series of biographies by the Christian book publisher Zondervan, who has also profiled Bono and football player Tim Tebow.

The subjects in this series are role models who are "working for the betterment of the world in which we live and who are motivated primarily by their Christian faith," according to Kathleen Kerr, an editor at the company.

The book begins with Palin's childhood in Alaska and shows that "with guts, character, determination and unwavering faith in God, even an ordinary person can change the world," Kerr said.

Author Kim Washburn was not granted an interview with Palin, but used her memoir "Going Rogue: An American Life" and news accounts to help her write.

She said she was impressed by Palin's work ethic and independent streak, which may resonate with young women, according to the AP.

The account does not include the saga around Palin's daughter Bristol and her high-profile pregnancy during the 2008 presidential campaign. 

"We tried to stay away from the super-heavy stuff," Kerr said.
