A howl. (Heart-rending too.) ""The wolf family lived in an abandoned powerhouse, high in the mountains."" When the wolf children ask why Christmas never comes there, Father Wolf heads for town--managing to pass unnoted in a trenchcoat, fedora, and dark glasses from the town dump. In a department store, though, he forgets himself playing with the toys--then (""Help, help! A wolf!"") disappears into the store-window winter scene. Dejectedly, he trudges home, present-less. ""Suddenly Father Wolf was blinded by headlights."" A truck hits him, and stops on the mountain's edge; he regains consciousness and howls--whereupon the terrified truck drivers leap out, the truck hurtles down the mountain. . . and spills its load of Christmas presents for the wolf children, and the other wild young, to find on the last, wordless page. Spare, expressive illustrations (shades of Harold Berson)--and a cockeyed, original, tender yarn.
