The Brightstorm twins are back for another adventure! Eudora Vane has organized an explorer fleet to search the Eastern Isles, the last known destination of missing adventurer Ermitage Wrigglesworth. Harriet Culpepper and the crew of the Aurora join the mission, but they don't believe that Eudora has good intentions. What is she really looking for?

The Aurora crew are going on a mission to the volcanic north, where years before the Brightstorm twins' parents discovered the moth that is their family symbol. But scheming, ambitious Eudora Vane is still dedicated to destroying the Brightstorm family name, and the further the Aurora travels, the more long-buried secrets are revealed.
