Mountain trolls, forest trolls, trolls who live under bridges, trolls with multiple heads, trolls with long red noses perfect for stirring soup — the husband-and-wife team of Ingri and Edgar Parin d'Aulaire knew their trolls intimately, and their beautifully lithographed illustrations bring these creatures to life in all of their delightful strangeness. A companion to their beloved Book of Norse Myths, this is the kind of book children pore over for hours and adults find just as captivating.
