The Princess and the Pauper, by Kate Brian
"It was very interesting. It would have deserved more stars (I give it four out of five) if Ingrid, Carina, and most of the people they hung around with didn't smoke; and if she didn't meet Ribbit and hang out with him while he was drunk." Reviewed by Jordan, Hemphill Teen Reader!
A light story generously peppered with modern-day references to movie stars, musical styles, and teenage slang, this novel is perfect for fans of Meg Cabot's "Princess Diaries" series ~ School Library Journal
