Why does my older sister have a perfect life? I'm Mackenzie Ziegler and I'm sick of being in Maddie's shadow. The people in school don't even know my name. They call me "The Girl that is Maddie's Sister." Maddie gets all the attention and has so many friends. She's a cheerleader, dancer and the lead of every school play. When Mackenzie makes a wish on a star everything changes. Will she be able to change things back before it's too late? Even if she gets her moment to SHINE will she be ready? Maybe she'll learn to be careful what you wish for. [cover by @madieexziegler]
