Leo Lionni’s Caldecott Honor–winning story about a little mouse who gathers something unusual for the long winter is celebrating its fiftieth birthday! Winter is coming, and all the mice are gathering food . . . except for Frederick. But when the days grow short and the snow begins to fall, it’s Frederick’s stories that warm the hearts and spirits of his fellow field mice.Winner of a 1967 Caldecott Honor, Frederick has been cherished by generations of readers. “A splendid achievement.” —School Library Journal, starred review “In Frederick, a mouse who is a poet from the tip of his nose to the end of his tail demonstrates that a seemingly purposeless life is indeed far from that—and that we need not live by bread alone!” —Eric Carle
