Oh, I liked this more than I thought I was going to, since this is not typically my favorite genre. But I found the characters to be likable, the pacing to be very engaging. By the end of the book, I wanted, no had to know, what was going to happen to Katy and Daemon and Dee. The best scenes were those where Katy and Daemon let down their defenses and communicate, and the action sequences are well done. 
 I liked the world building here too. Looking forward to Onyx. 
 A solid 4 out of 5 stars for me on this one.
