For starters, this topic isn't about former or non-practicing JWs, but active ones who are authors. We all probably have heard of McMillan's Faith on the March and the other one by Marley Cole, but how about more recently?
I found a couple. The first appears to be a life story from someone who owns a mailbox company, correct me if I'm wrong.
"Jocko: The Last Trumpet" (weird name, right?) available on Amazon
and also for free online on the authors site
Another one, which may or may not be fiction, is titled "Tower". From the description it's hard to tell if it's pro-JW or anti-JW. From Lulu:
Anybody familiar with these books or know of other active JW authors?
