2.5ish... 
 So the best thing about this book were the AI's and the robots. Very well thought out, and pretty creepy. 
 The romance.... Not quite tangible. And it disturbed me a little, the fact that Lor thought she was a robot (even after hanky panky - I mean come on) and pursued the relationship so much.. I probably just haven't read enough sci-fi, but that little fact didn't sit so well with me.
