The ragtag crew of Captain Harriet Culpepper is off on another adventure! Ermitage Wrigglesworth, the notable explorer and author, has been reported missing in Stella Oceanus to the east. Twins Arthur and Maudie are eager to answer the call of adventure to find him, but their old nemesis and newly discovered aunt, Eudora Vane, is also on the hunt. As Lontown’s most famous explorer families set sail aboard their sky-ships, it soon becomes clear that Eudora’s not just after the missing explorer. There’s a secret she’s chasing, something Wrigglesworth had discovered before he vanished, something that definitely shouldn’t be in Eudora Vane’s hands. The Aurora’s crew will have to journey to uncover Wrigglesworth’s secret first, and will discover new lands and new friends along the way. . . .

Return to Vashti Hardy’s “marvelously imagined” world (Publishers Weekly) in this sweeping and propulsive follow up to Brightstorm, hailed by the Bulletin of the Center for Children’s Books as “a novel of grandeur and action.”
