Hope this is the right page for this.
I have a hardcover copy of The Art of Legend by Wesley Chu published by Del Rey. When I looked up my book’s ISBN I didn’t find anything. I saw that there was a hardcover edition of the book published by Del Rey here (https://www.goodreads.com/book/show/2...). That book doesn’t have the same ISBN number as my copy. I assume either the ISBN of this version is incorrect or I have a different edition. Please advise me if I need to request this addition added on a different page.
The ISBN of my copy is: 9781837840540

P.S. The page number is also different, my copy has 607 pages

Thank you
