To answer this, we need more information. There are many books with the title "Lightning".
Please provide more context, such as:
* The author of the book: This would help narrow down the search.
* The genre of the book: Is it fiction, non-fiction, children's book, etc.?
* Any other details about the book: Is it a recent publication? Is it a physical book or an ebook?
Once you provide more information, I can help you determine if the book you're thinking of is an AR book.
