'Tween movie alert! Top teen Hilary Duff stars as a Valley-girl Cinderella! Once upon a time: Samantha, a San Fernando Valley teen, lived with her widowed dad. Then, he fell into the marital clutches of an evil stepmom. Now, Sam’s at the mercy of her step-monster, and stepsibs. A ray of light is her IM buddy, a guy who calls himself Nomad. They agree to meet at the Halloween ball-only when he’s revealed to be the school’s hottie football star, she panics and bails at the last second. His only clue to finding her? She dropped her cell phone. Happily ever after: Scholastic’s Cinderella Story scrapbook is an excellent pin-up-able movie keepsake.
