Unable to add new edition

[D.]

I seem unable to add a new edition of this book because it tells me the book already exists. I'm especially interested in adding a new cover photo. Please help! Thanks!

On Goodreads, only one book record is allowed per ISBN or ASIN. Furthermore, Goodreads policy is to keep all published covers because users like to shelve the edition that matches the one they own. If a book is reissued with a new cover but an old ISBN or ASIN, we create an alternate cover edition (ACE), and you as the author have the ability to set the new cover as the default edition. I have created two ACEs for your book here:

https://www.goodreads.com/book/show/2... (kindle)
https://www.goodreads.com/book/show/2... (paperback)

To set either as the default edition, follow the instructions here:
