High school freshman Delia Blaine is fascinated by her new friend, Amandine. An artist, a dancer, an actress, Amandine never fails to astonish Delia with her bold, thrilling antics. Her skits and stories keep the school day fun and unpredictable, and draw shy Delia into a compelling word of make-believe. But as the games get more daring and strange, and Amandine's stories become disturbing and wild, Delia begins to mistrust, and then to fear Amandine. But it is not until Delia finds the strength to break away that she realizes how tightly Amandine has pulled her in, as she must face down Amandine's twisted revenge.
