The King's English Bookshop

When an immaculately dressed woman steps out of an iridescent bubble and asks you if you’d like to become a substitute princess, do you: a) Run b) Faint c) Say yes!
For Desi Bascomb, who’s been longing for a bit of glamour in her Idaho life, the choice is a definite C—that is, once she can stop pinching herself. As her new agent, Meredith, explains, Desi has a rare magical ability: when she applies the ancient Egyptian formula Royal Rouge, she can transform temporarily into the exact look-alike of any princess who needs her subbing services. Dream come true, right?
Well, Desi soon discovers that subbing involves a lot more than wearing a tiara and waving at cameras. Like, what do you do when a bullying older sister puts you on a heinous crash diet? Or when the tribal villagers gather to watch you perform a ceremonial dance you don’t know? Or when a princess’s conflicted sweetheart shows up to break things off—and you know she would want you to change his mind?
