Necropolis by Jordan L. Hawk
I liked this one. It wasn't very Whyborne and Griffin centered, it was a Christine story and I like her so much, I loved to know more about her and see her character develop. You get to see there's more to her than being Whyborne "partner in crime"
The story the book tell us is very predictable, though. I knew from the start who was the villain in this book, but despite that, I really enjoyed the read, with its new characters, change of scenes and all the possibilities that give us plot wise.
