""It was a huge and powerful ship with a tall, handsome pilothouse and big smoking stacks, no place for a girl, though I loved it, I cannot tell you how much I loved it."" In her eighty-fifth year, Fern Halvorson tells the story of a childhood journey across Lake Michigan and the secret she has kept since that ill-fated voyage. As his wife lies dying in the brutally cold winter of 1936, Henrik Halvorsen takes his daughter Fern away with him. He captains a great coal-fired vessel, the Manitou, transporting railroad cars across the icy lake. The five-year-old girl revels in the freedom of the ferry, making friends with a stowaway cat and a gentle young deckhand. The sighting of a ghost ship, though, presages danger for all aboard.
