Rachel's books

Devin has a demon blade.  This blade is like a sentient being.  It hungers for chaos, so Devin uses it in a productive way and helps people in trouble.  Natalie is in the wrong place at the wrong time. Or is she?  Devin uses it to dispatch her would-be assailants. 

I liked that Natalie's background was questionable.  I liked that she was doing better. She's got some attitude (but not enough that she was a bitch/unlikable).  I did think she should have caught on sooner then she did.  Both she and Devin work together nicely.  I also liked the end.
