Ruby in the Smoke

I just found out that Billie Piper is Sally Lockhart in The Ruby in the Smoke. I'm actually about 50 pages away from the end of the Shadow in the North.

I NEED to see Ruby in the Smoke. If you find it PLEASE post it! The two books are turning into my favourites and Billie Piper is one of my favourite actresses as well.

I'd also appreciate some opinions on it. Was it any good? I'm sure it was. But I think I'd like to know as much about it as possible!
