Former Alaskan Gov. Sarah Palin has signed a deal to write another book, publisher HarperCollins announced Wednesday.

The publishing company says the still untitled book will focus on Palin's political and spiritual values.

"This is the idea which appealed the most to her," HarperCollins publisher Jonathan Burnham said.

The 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 HarperCollins said in a statement.

Her first book, Going Rogue, has sold more than 2.2 million copies and spent six weeks at the top of the New York Times bestseller list.

Meanwhile, talk also abounds that the former Alaskan governor may be considering starring in a reality TV show.
