The Third Sister ~ Mason Ziegler

Growing up in Maddie's shadow is hard, but growing up in Maddie AND Mackenzie's shadows? It can be a nightmare. As the youngest, Mason's always felt invisible next to her sisters. Once they left the show and moved on, Maddie and Mackenzie's careers took off, leaving Mason at home to practically raise herself. Now that her sisters' lives have finally settled down a bit, they've been able to return home and go back to school. Now, at 14, Mason is starting high school at the same school Maddie (17) and Mackenzie (16) go to. Will this be the year that everything changes?
