If you've read the first book you will certainly love this one, but even if you haven't read it you will still enjoy it very much.

It ties into lord loss brilliantly but if you havent read Lord Loss then it wont matter, but it makes you go "oooooh!" if you have read it.

It's still on the subject of demons but completely different characters apart from the odd one and its just amazing what Mr.Shan can do with a computer and himself.
