It’s all about the names of the various Popes and their extremely interesting history. Give that we have just elected the very first Francis (and recently had the very first and second John Pauls), I recommend checking it out! I’m particularly thrilled that there was a Pope Lando, presumably the bishop of Cloud City on Bespin.
Anyway, check it out! You can get your copy here, where you can link to the Kindle, Nook, and Apple iBooks versions, as well as get more info.
