I'm in Wilmington, North Carolina right now (where the temperature as of 9:30pm Eastern time was 90 degrees) to interview a couple whose daughter brought home a book a few months ago called "King & King," which was included among the choices in her public school's advanced reading class list.
It's about a prince who, despite his mother's best matchmaking efforts, "never cared much for princesses." But then he meets the brother of one of the princesses--Prince Lee--and finally falls in love and gets married. The book ends with a kiss between the two princes.
The class with this book on the reading list is a first grade class. The book is written for ages six and up.
