Sarah Palin’s “gay friend” got a lot of press when the vice-presidential nominee was on the campaign trail — even if no one ever figured out who she was.

Now, in her new book, Going Rogue, Palin sheds more light on this mystery friend, according to a review of the book in The Wall Street Journal.

“She writes with sensitivity and affection about her gay college roommate,” Melanie Kirkpatrick writes, ultimately saying the book offers “criticisms” of the McCain campaign and “self-criticisms” of her performance on the campaign trail, but reads like one long stump speech.
