A nice ending to a good series. I love Royce and Hadrian, and enjoyed being immersed in their world again. The story wraps up a little too perfectly and is fairly predictable based on what went before, but the story flows, and there's non-stop action and intrigue. The character interaction is very good, as usual. And the schmoop didn't make me run from the room screaming!

I have to say I couldn't have predicted Nimbus.
