NEW YORK - Former Republican vice presidential candidate Sarah Palin will come out with a new book that is a "celebration of American virtues and strengths," publisher HarperCollins announced on Thursday.

The as-yet untitled book by Palin, widely considered to be weighing a run for U.S. president, will feature selections of readings that have inspired her and portraits of people she admires, the publisher said.

"She will also draw from her personal experience to amplify these timely (and timeless) themes," HarperCollins said in a statement.

Palin's first book, "Going Rogue," has sold more than 2.2 million copies, HarperCollins said.

Palin ran unsuccessfully for vice president on the Republican ticket with presidential nominee Sen. John McCain in 2008. She was governor of Alaska at the time.

Since then, Palin resigned as governor and has made public appearances before such groups as the conservative "Tea Party" movement and on NBC television's "Tonight Show."

She also has been hired as a commentator on Fox News, where she recently said she was open to a possible White House run in 2012 but had not made up her mind.

The publisher, part of Rupert Murdoch's News Corp empire, did not disclose the amount of Palin's advance for the new book.
