Best book in the series!! I didn't think it could get better until it did. I'm simply overwhelmed by all the praise I could heap onto this book. It could possibly be the best book I've ever read. Therefore, I will say a simple... Thank you Kim Harrison. Please write the next book quickly. Until then, I think I'm going to have to read this book again very soon, even though I never read a book again unless its years later. 
 Edit: 
 One thing that I do want to comment on in particular is the fact that I had been waiting for Trent's character development for AGES! So, this was a major reason I liked Pale Demon so much. I've been drawn to Trent ever since Rachel was locked in his office. His character has been so mysterious and compelling and with such history and tension between him and Rachel how could I resist. 
 The same can be said for Al's character development. I loved seeing a whole new side to him. Kim described him exactly as I imagined. I guess I'm fascinated by evil characters (or partially so ones). 
 I'm just amazed at how Kim Harrison manages to make the plot-line come together so well after so many years of books and writing. I'm also amazed how consistent she manages to be. I can't think of any other series, that runs for such a long time, that manages it. She really is a great writer.
