This book is in the same universe as and takes place after The Airship Pirate Chronicles. It's also the first book of a new series. I read a print edition and that's where the only problems were. Some paragraphs were duplicated. Some words had missing letters. And there were some spacing issues. So just print editing things is why I'm saying four stars. The story was engaging and entertaining. I read it in four days because I kept loosing track of time and reading longer than intended. If you like Capt. Robert's other books and especially if you remember the RPG's Spelljammer or Space:1889 (if you know, you know), then you should check out Sailing Deep Sky.
