Bristol's Memoir Yanked Off Amazon.com

Bristol Palin's memoir has mysteriously vanished from Amazon.com's listings nearly as fast as it appeared. A pre-order page for an "Untitled Bristol Palin Memoir" to be released in June was available earlier this week but now appears to have been pulled, AP reports. A publicist at HarperCollins, Bristol's presumed publisher, declined to comment.

In an interview with E! Online, the 20-year-old Palin said writing a book is something she hopes to do in the future, along with going back to school—and running for office. Palin said she'll "probably" follow in her mom's footsteps and enter politics someday. "If I saw something that needed to be changed, then I would step up to the plate and do something about it," she said.
