Seems like a former confidant to Sarah has written a book. Here's the press release:
In BLIND ALLEGIANCE TO SARAH PALIN: A Memoir of our Tumultuous Years, Bailey explores such key events as Palin’s gubernatorial victory, Troopergate, illegal coordination with the Republican Governor’s Association, never-before-revealed scandals such as a judicial appointment as payoff for a favorable child custody ruling for Palin’s sister, the vice presidential campaign and the bizarre vetting process, and Palin’s resignation. Drawing on thousands of emails from the personal accounts of Sarah and Todd Palin as well as key members of the staff, Bailey reconstructs how the Palins’ pathologies became apparent, and how he and other members of the team rationalized Sarah’s increasingly erratic behavior and their commitment to a cause that was changing shape before their eyes.
Some parts of the book have been leaked. I'm trying to find them.
