I'm in a bit of a pickle. So I've been doing side quests for the past few days and I've got Books 1 through 11 fine, except for Book 7. I'm not asking where every single quest is, but can someone please tell me all of the islands that the quests are on? Or at least the skyways?

I've checked all of Big Sky and Haunted Skyway so far, and nothing's come up. Is there a bar in Big Sky that I didn't visit?
