As a Spartan, he is dedicated to the fight, but we have no idea how far his dedication goes. Now we get an idea. It's obvious he loves Gwen, but could he really just leave her? (I won't tell!)
As far as bridge books go, I appreciated that this just didn't retell a scene from his perspective. It actually extended the story a bit as well. There was new action that I had not seen before. I am anxiously awaiting my chance to read the next book, Midnight Frost.
