In this sequel to The Voyage to Magical North, Brine, Peter, Cassie and crew return for another swashbuckling adventure on the high seas. Reaching the edge of the world can’t stop the crew of the Onion! It’s westward ho in search of dragons, no matter the obstacles. And there are obstacles. Flesh-eating vines, violent locals, and mischievous magi―not to mention Marfak West’s ghost―meet the pirates when they land on the Western Island, where a volcano threatens to end them all. Together, Brine and Peter might just be able to save the crew, the island, and themselves. Or they might all go up in flames. It really could go either way.
