Walker, Shiv, and Genoa are marooned on Plumb Island with the crew of the Jacklight, their ship in tatters.
As they plan their escape, Walker corresponds with his grandfather using his sea-faring message jug.
He learns that a gold-trimmed ship, billowed in storm clouds, has arrived in Winooski Bay. And one of its passengers is a clairvoyant woman who knows the secrets of Atlantis - and she looks exactly like Genoa. Drawing from sources as disparate as Tintin, the Iliad, Kidnapped!, and Moby Dick, Renier has woven together a breathless tale that will leave readers with their ears ringing from the cannonshot, and their eyes dazzled from the glowing stares of seawitches.
