To say that Azure Brine is at odds with her father would be an understatement. A new governor has emerged in the League of Islands, and her father has completely bought in to his "Humans First" rhetoric, pushing their once-strong relationship to the breaking point. Their connection is truly put to the test when her father decides to join the governor's ship on a voyage to the Capitol Isles for the inauguration. But when Azure learns the governor has nefarious plans for the islands, and that her father is in danger, she and her best friend (a foul-mouthed bird named Robin) set out across the archipelago to save him.

Along the way they meet a reanimated skeleton with confidence issues, a group of pirates who just want to sing and have adventures, and...a dragon.
