'Literary' and 'artistic' and leaden, this involves two Viking children who, borne away by a huge black bird and dropped into the dwarfs' net, undertake the care of a baby that felt down before them. He is not ""the child of earth people"" (he rejects reindeer milk) or of dwarfs (ditto the eggs of the sea tern) but he thrives on the milk of the giants' great cow -- and they, in gratitude for his safekeeping, will return the children to their valley and hold frost back from it. The telling aspires to poetic antiquity, the illustrations to. . . surreal horror? (The nude dwarfs look like the decay of Dorian Gray.) Wrack and rune -- or the sort of thing that leaves children cold.
