For midwesterners – I’d also recommend the Midwest Book Award. I agree with Maria – My first book won an IPPY Award (independent Publishers) and my last book was a finalist for a Midwest Book Award. Both organizations have stickers (electronic and paper) you can purchase to put on your books. I find I have gotten more traction from award books from individuals than organizations like bookstores or libraries but then I don’t know who has taken a second look but didn’t decide to pick up my book, and I consider second looks a good thing too! 🙂
And remember – most (if not all) awards can only be entered for the book published the previous year e.g., 2016 award for a 2015 published book. Application dates will vary depending on the award so check them out in the fall of the year you published your book. You may have until the spring to enter but you may not.
