Leo Lionni’s An Extraordinary Egg: The 20th Anniversary Edition (Alfred A. Knopf Books for Young Readers, 2014) will enchant readers young and old as much now as it did in 1994 when this simple fable was first published. The picture book tells the story of what happens when three friendly frogs find an egg from which hatches a green scaly animal they guess to be a chicken. This case of mistaken identity will provide children with endless amusement, especially when baby and mother are reunited, and mom greets her child with, “My sweet little alligator.” Ages 3–7; $17.99.
