A clever prince was riding through the woods one day, when a piece of paper floated down to him from window very high in a tower. It was full of mathematical calculations. He wondered how the paper got from the top of the tower to him. He began to solve this puzzle.
In this book not only are there several options of voices but both guys and girls can relate. It is not just about the prince or the princess but about both of them which I think really helps kids.
