I think there was a great improvement to the first book. Katy and Daemon really have some hell of chemistry and I love them being together (when they're not about to rip each others throats out). I also like the story, cause it's pretty new to me, that aliens can be that cool and sexy and lovable. 
 Having Dee for a BF - please yes! 
 At some points it was kind of boring for me - i easily missed either some action or daemon, but all in all this was again very fluently to read once you drown in this book.
