Getting the book (tentatively titled The Scion) in the hands of beta readers is a huge milestone for me because I do not use alpha readers. That means, the first two people who will ever read it, now have it. (Well, actually, one of them does. The other has to wait for it to arrive in the mail.)
So while the beta readers are doing their thing, I have time to do some other projects: short stories and outlining more books in this series. Writing is fun!
