You know, for a supposed emotionless, killing machine reboot, Wren sure has a lot of fucking emotions. And gets punched and shot. A lot. 
 It wasn't a terrible book- I liked it enough to finish it in about 3 days, but I wanted...more. I wanted a ruthless killer and a badass heroine. What I got was a softie that fell in love with a softie. Bleh. I could have done without a love interest, too. 
 I'll read the next one, whenever it comes out, but probably not since I'm assuming I'll forget everything about this book within a week.
