wow! WOW!! This was an absolutely amazing book. I think in one fell stroke this has easily become my favourite book of the year. I wish I would have written this, it's that good. Victorian/ gothic/ mystery/ steampunk/ spy thriller meets hunchback of notre dame/ phantom of the opera/ and frankenstein. If I could give it more than 5 stars, I would.And now I have to wait, likely, more than a year for a sequel! Whinge!!!!
