A Russian tsar tells each of his three sons to shoot an arrow and marry the woman he finds where the arrow lands.

Imagine the feelings of the youngest son when he discovers a large frog holding his arrow in her mouth.

He marries the frog, only to discover that each night she changes into a beautiful princess.

But will he ever have a flesh-and-blood human wife to call his own...?

Virginia Lee's haunting, other-worldly illustrations transform Antonia Barber's elegant retelling of a Russian folk tale into an enchanting fairytale classic.
