Check out the July 8-9 Wall Street Journal for a review of four new Jane Austen books, including The Making of Jane Austen. Reviewer D. J. Taylor calls the book "fascinating." (Okay, okay, he also calls it "quaintly demotic," but I'll take it!) Although the article is behind a paywall, you may get a glimpse of it here.
