28. Avalon High

This is the book the Disney movie Avalon High is based on. If you've seen the movie; sorry, but in the book, Ellie's not really King Arthur. So here's what it says on the inside cover:
Avalon High seems like a typical high school, attended by typical students: There's Lance, the jock. Jennifer, the cheerleader. And Will, senior class president, quarterback, and all-around good guy. But not everybody at Avalon High is who they appear to be... not even, as new student Ellie is about to discover herself. What part does she play in the drama that is unfolding? What if the bizarre chain of events and coincidences she has pieced together means-as with the court of King Arthur- tragedy is fast approaching Avalon High? Worst of all, what if there there's nothing she can do about it?
This book is by Meg Cabot, author of The Princess Dairies,and lots of other books. It's 288 pages long, and an all-around GREAT book.
