Kevin Brennan Writes About What It's Like
I found this site in my wanderings and decided to give it a try. It’s called BookPinning.com, and for free it will feature your book cover image and link of choice (e.g., to Amazon). There are also some paid options, like Book of the Day, which apparently gives you a larger image at the top of the page.
Every little bit helps, I’m thinking. Check it out!
