A Russian czar tells each of his three sons to shoot an arrow and wed the woman he finds where the arrow lands. Unfortunately for the youngest son, his arrow lands beside a very small, very ugly frog. Alas, his father is firm, and he marries the frog. Each night, the frog changes into a beautiful princess, but still he wonders: Will he ever have a flesh-and-blood human wife to call his own? Virginia Lee’s haunting illustrations and Antonia Barber’s elegant retelling transform a Russian folk story into an enchanting fairy tale classic.
