Mr. Wooding wrapped this one up in a great big bow. If this is or isn't the last of the Tales of the Ketty Jay, it has been a great ride. This is a great steampunk adventure series. All the staples are there: airships, air pirates, magic/science mix. In addition, there are some fantasy elements as well. I would suggest starting with Retribution Falls, rather than jumping right in to The Ace of Skulls.
