Degree Press, like all independent publishers, is always looking for ways to market books. If you have the sort of book that lends itself well to reading groups (read: fiction), you should consider creating a guide for reading groups (and then, of course, reaching out to reading groups to choose your book).
ReadingGroupGuides.com is a site with many, many such guides and the vast majority of these guides have been supplied by the publishers. A cursory look shows that almost all of the guides are for fiction. Given that a reading group will purchase a bunch of books, this could be a good place to spend time in your marketing efforts.
