Sarah Palin is ready for the next chapter of her publishing career.

Publisher HarperCollins announced Wednesday that the former Alaska governor and Republican vice presidential candidate is working on a "celebration of American virtues and strengths." No release date has been set for the untitled book.

Palin's memoir, "Going Rogue," which HarperCollins released last fall, has sold more than 2 million copies. Her new work will "include selections from classic and contemporary readings that have inspired her, as well as portraits of some of the extraordinary men and women she admires and who embody her love of country, faith, and family," the publisher's statement reads.

"She will also draw from her personal experience to amplify these timely — and timeless — themes."

In an e-mail Wednesday, HarperCollins publisher Jonathan Burnham said that "a number of ideas and concepts" were explored with Palin. "This is the idea which appealed the most to her," he said, adding that she is "gathering ideas and identifying favorite texts and examples."

Burnham declined comment on financial terms. As with "Going Rogue," Palin was represented by Washington attorney Robert Barnett, whose clients include President Obama and former President George W. Bush.
