While I liked certain concepts of this book, overall I was just way too confused. There is no real world-building. It just tosses us into this strange world, quite different I must admit, and expects us to keep up! I had no idea what a lot of things refeered to or why the world was the way it was or what was really going on very well. This left me a bit vexed and almost constantly questioning what was going on. This might have made sense if it was a second o third book of a series and the author had jumped in, expecting the reader to have read the first book. But no, this IS the first book. 
 What I did like: Grey's character. Very independent, and caring. Bit reckless though. The writing is engaging and if I understood what was happening and had some backstory I think I would have been hooked. 
 Overall, disappointing but author has some potential. I would give her another chance still.
