I finally read it!! I don't know why it took me so long, I LOVE LOVE the Lux series and I've been going through major withdrawal waiting for the next book. 
 And I'm very very glad I read it!! It gives so much more insight into why everyone was so hostile to Katy in the beginning, what happened to Beth and Dawson, and about the other Luxen. 
 The Only reason it's not a five star for me is because I much prefer reading about Daemon and Katy to Dawson and Beth. Yeah Beth and Dawson were very adorable and so fun to read about but I miss the banter, arguing, and witty humor between Daemon and Katy. 
 So four stars, because less Dawson and more Daemon for me.
