Scott O’Dell’s book The King’s Fifth is about Spanish conquistadors seeking gold in the New World. It bounces between the young map-making narrator languishing in jail for trying to defraud the king of his share of the gold and telling the story of how they found it. It’s a tale of casual brutality towards the native people, and abandoning your dreams for greed (but then redeeming yourself in the end once everyone has died).
It wasn’t bad, just predictable. The blurb on GoodReads seems to be from a time when casual genocide was still considered heroic. Hm. I didn’t realize until just now how old this story was since my copy was an ebook. I don’t think that makes much of a difference to my response.
