The Dauntless cover is here. I love it! In the original mock up cover, I loved the composition, but the model didn't quite fit the description in the book. However, after a few little tweaks by the publishing house, I couldn't be more pleased :)
Dauntless will release next March, so yes, you still have to wait for a while. In the meantime, you can get more info about the book and the series at http://valiantheartsseries.blogspot.com/ and if you'd like, you can actually pre-order it already in the paperback here.
