FERGUS CRANE! YOU ARE IN GREAT DANGER! I AM SENDING HELP.
Signed T. C., your long-lost Uncle Theo
Fergus Crane has an almost ordinary life—having lessons taught by rather odd teachers on the school ship Betty Jeanne and helping his mother in the bakery. But then a mysterious flying box appears at the window of his waterfront home and Fergus is plunged headlong into an exciting adventure! The box is followed by a winged mechanical horse that whisks him off to meet his long-lost uncle and his penguin helpers, Finn, Bill, and Jackson. Fergus finds out that his teachers are not quite what they seem— they’re actually pirates! Can Fergus and his winged horse save his schoolmates on the far-off Fire Island? And who else will he find there?
