Will Tina Fey be in it? Gov. Sarah Palin has signed on to write a memoir for HarperCollins for an undisclosed amount. The Alaska governor says she sees the book as an “unfiltered forum to get to speak truthfully about who we are and what we stand for and what Alaska is all about.” She tells the Anchorage Daily News that she’s excited to put her journalism degree to work in penning the book, though a collaborator will help her write it. The book will address her time as mayor of Wasilla, as well as her rise to fame during the presidential election as Sen. John McCain’s running mate. Palin laughed off rumors this January that publishers were offering her an $11 million advance for her story, but she won’t disclose the amount she’s been paid by HarperCollins, saying she wants the focus to be on the content of the book. Ubiquitous agent Bob Barnett secured her the deal.
