I like the way that she developed the characters. Some authors seem to feel the need to over-develop their characters and that gets tedious and boring for me as a reader. Black, however, does a marvelous job. She makes the characters believable, well as believable as "workers" can be. You find yourself sucked into the world of Cassel and all of his "friends".
The only criticism that I have for this book is that it was somewhat hard to follow in the first few pages. Once I figured out what was going on though I had a hard time putting this book down. There are many twists and turns in the story line that keep you guessing from the beginning to the end. You have kind of a hard time figuring out who really has the upper hand in the story, which makes for a great ending. I can't wait to get my hands on the second installment of this series.
I would recommend this book to anyone that is looking for something a little different than the vampire and werewolf books that are so popular these days.
Overall rating: 4/5
