Another book about a writer writing

My friend, Ray, just lent me a book. She thought of it when I was on my search for books about authors writing for my Going It Alone query letter.
The book is called The Thirteenth Tale by Diane Setterfield. It was #1 on the New York Times Bestseller list. And it has a wicked cool cover of old books piled up, which is actual what interested Ray about. Yes, she judged a book by it's cover but she says it's because she's an artist, thus she judges everything visually to some extent, and therefore is excused. Or something like that.
Anyway, I'm only a few chapters in but I'm intruiged already. I'm excited that it's not only about stories an author wrote but it's main character helps run a used/antique book store. There's lots of talk about selling old books, which definitely interest me since owning a successful book store is right up there with becoming a successful writer.
I'm curious to see if this book will be something to mention in my query letter. I'm not sure that the Golden Notebook is the right thing, seeing as how it's older and gives very high standards to live up to since it was written by a Nobel Prize winner. So maybe this book will be a better reference.
