The cover does a great job of conveying the contents and drew me in before I had even opened a page. A pirate ship under a dirigible? Cool and add to that a pirate captain every bit as charismatic as Jack Sparrow and there stands Captain Bonny, who has just stolen a whole load of opium.
The story flows above various areas of England and France as various characters interact with each other. They are pirates for the most part so can't be expected to behave as if in polite society encountered below and that makes them so much fun. The leap out of the pages, each with a very credible life and personality.
I haven't read a lot of steampunk books, but of those I have, this stands in my high regard. There is something inherently fun about the genre and the intrepid characters featured. This book may well turn out to be my favorite read of the year.
