Everyone is magical in the Kingdom of Zephram. Everyone, that is, except for the Royal Quadruplets.
So even though Tom, Lizzie, Ned and Nell are princes and princesses, the brothers and sisters are pretty lonely. The castle children won't play with them, and the rest of the kingdom wonders what to do about them, too. Because if they're not magic, what can they really do?
But when evil Prince Persius steals the magic Golden Ball of Zephram and holds the country ransom for a Month of Zephram Mondays, the brothers and sisters are the only ones left who can try and save Zephram!
Maybe being magical isn't so important after all!
