This really was like netgalley described. The fast and the furious crossed with fourth wing.

I loved this book so much, I hope there is a second. There was action, spice, betrayal, and I really enjoyed the story. I loved the characters and thought they were all cleverly interwoven. I did kinda guess who was stealing the obsidian, but it didn't take away from the ending at all. 

Seriously, if you liked fourth wing, how to train a dragon or fast and the furious, give this a try. You won't be disappointed.
