Book cover: Melancholy beach

The client is an author looking for an appropriate cover for a soon-to-be-published novel. The story takes place around a beach, but not the fun sunny beach where you go with your family. This beach must be lonely and forlorn. The client has not decided if the cover should wrap around the book, so vertical and horizontal images are acceptable. HOWEVER, horizontal images must have the center of interest on the RIGHT half of the image so it would appear on the cover.
