It's been a while since I read anything by Jane Austen but I enjoyed Austenland by Sharaon Hale as much as I have enjoyed other books by Hale.
Austenland is a light hearted story about Jane, a young woman who might be a bit more obsessed with the world of Jane Austen than is healthy. She inherits a trip to escape into the world of Austen. She gets to dress, talk, and eat in the manner of time. She finds herself again and maybe love as well.
