This is a WordPress plugin, what it does is it allows you to craft and post a book or books on your site. Of course, you do need to pay a fee to do the latter.
Of course, I do get a commission for each license bought, and I could use the money. That said, I do like what BookPress does and may soon have a book up here. So if you are open to self-publishing and you use WordPress give BookPress a try.
