Airhead

Two worlds collide when super-gorgeous celebutante Nikki and tomboy brainiac Em find themselves thrown together - literally. Forced to live the life of a glamorous supermodel, will Em be able to keep her old life, and those she cares about, a secret? Airhead is the first in a brilliant, funny and thought-provoking trilogy from Meg Cabot, the author of the million-selling The Princess Diaries.
