3.5 STARS. I don't read much in the sci-fi realm. I didn't even know that I was dealing with an alien race until I was half way through the book. I'm glad of it because I adore Dee and Katy. I'm still a bit peeved at Daemon and his hot/cold behavior toward Katy. 
 I'm a lover of UST and this book has it in spades, plus two sarcastic and sassy characters that are driven by passion and self-defiance. 
 Just a bit more of backstory for each of them might have pushed me closer to 4 stars. A fun read for me and I am moving on to book 2 immediately.
