2.5 stars. 
 This was... fine. The first third took me a bit to get into, but once our motley crew was assembled I sped through the rest of it. But at the end of all of it was just okay. 
 As many people have mentioned Laini Taylor's Daughter of Smoke & Bone does this all much better. To the point where I was less than 25% done with this book and I could predict where things were headed. Now, that doesn't have to be a bad thing, and honestly Grey does a good job laying down the groundwork for you to follow as you go... but it was really obvious. 
 I don't know. Mostly this was just average and forgettable, save some of the intriguing worldbuilding. I don't really care about the plot or the characters enough to soldier through two more books of this, so I'd say skip it and read DOSAB instead.
