First of all, I want to say a big "thank you" to everyone who has taken the time to share her or his thoughts. I've made a point to stay out of the debate. I will, however, throw in a few related points.
1- The purpose of a book cover is not to "reflect the story." (This comes not from me, but from a friend who has been a successful professional cover artist in the spec-fic genre for a very long time, and has even won a Hugo Award. Nothing sets him off like this particular objection.) There are a number of reasons which I won't go into, but foremost is, the person who has not read the book has no idea if the cover reflects the book until he or she has finished reading it. Suffice it to say, the purpose of the book cover is to entice the potential reader to pick up the book (or click on the link), and read the synopsis and blurbs. The synopsis, blurbs, previews, and reviews serve to reflect the story.
2- Yes, the cover is somewhat generic, but that's actually fairly common in fantasy today. The cover of The Silver Serpent is simply parchment with a fantasy-esque font, and it's our best-selling spec fic title. As for the proposed title, I'm quite confident that the overall quality is head-and-shoulders above what you'll find with a vanity press, though the point is well-taken.
3- The discussions have illustrated the problems inherent with a custom cover, especially with this particular novel. We must put ourselves in the mindset of a reader who knows nothing about this book, and think about the suggestions we've discussed. A silver necklace, though certainly connected to one element of the plot, might suggest romance rather than Tolkienesque fantasy. If we go with a seabird, does the artist paint it according to Sherry's vision- an iridescent osprey with an owl's head? What does the unsuspecting reader think of that? Does such an image fit with the entirety of the novel? On Sherry's blog, others have suggested a beach scene with a sword, necklace, and seabird. Might not that cover suggest historical romance more than fantasy?
While all of the suggestions are certainly connected to the plot of the story, do any of them even hint at the depth and epic scale of Seabird? I am not suggesting that the new cover captures the scope of the novel, only that it is a clean, crisp cover that might entice a reader to take a closer look, which is what we are looking for.
Again, thank you to everyone who has taken part, and will continue to take part, in this discussion.
