Publisher's Summary
Before the Black Pearl, there was a teenage stowaway named Jack Sparrow…

Jack and his crew return to New Orleans to find the entire city covered in precious metal—and ruled over by the nefarious Madame Minuit. Can the combined crews of the Barnacle and the Fleur de la Mort defeat Madame Minuit and her powerful allies?

Summary
City of Gold is basically one big continuation of Silver- lots of fight sequences and hostage-passing back and forth. Jack fights Madame Minuit in a final showdown- barely escaping with his life, but victorious nonetheless. At the end of the book, it takes a twist ending with all of Jack's crewmembers/friends going back to their respective homes- save Fitzwilliam, ironically. He and Jack banter back and forth about Fitz's watch, when, in another dramatic twist, the fearsome Davy Jones surfaces beside the Barnacle and demands it.

Note: Some of Jack's teeth, previously turned to bronze in the previous story, permanently turn gold when the gems of the Suns-and-Stars are knocked out. This is yet another of his now-famous traits as a pirate.
