It's a violation of the first sale doctrine. They can ask, but cannot legally prevent the resale.

The first-sale doctrine creates a basic exception to the copyright holder's distribution right. Once the work is lawfully sold or even transferred gratuitously, the copyright owner's interest in the material object in which the copyrighted work is embodied is exhausted. The owner of the material object can then dispose of it as they see fit. Thus, one who buys a copy of a book is entitled to resell it, rent it, give it away, or destroy it.

Decline the license. Now you are limited to just the basic rights that copyright law gives, which includes the ability to resell or lend the book.

I once visited the web site of an author whose series I was enjoying and was surprised by her angry insistence that selling used books is theft because the author doesn't get a cut. Never bought the rest of the series. It just felt weird.

This book may not be re-read. If you plan to read it more than once, please purchase an additional copy for each read-through.
