Can multiple people review the book?

Multiple people can participate in the review process simultaneously, but only one copy of your book can be in the library at a time.

You will receive an email as soon as your book gets checked out for review. At that time, you can publish your book in the library again provided you have enough tokens to do so. If you are quick about republishing your book to the library it's possible to have many reviews being submitted at the same time for one book.
