I mostly really enjoyed this book. I really like Cherry and her staff. I'm less sold on the two male interests.
Cherry is a great steampunk lead. She's an independent woman who is very interested in the world around her and in science in particular.
I really like the world Cooper has designed. The wealthy literally live above the poor because the buildings of the peerage have been raised up on stilts while the poor live in a London covered in smog that makes it hard to breathe.
