Michaela is a junior in high school, living with her single mom. Her dad lives a few towns away, and she only sees him on holidays and birthdays. They barely know each other, but Michaela is so close with her mom that she's never minded. That is, she didn't until her mom dies suddenly. Now Michaela has to move in with her dad...who reveals that he's been married with kids all this time and that she's the product of an affair. Before she can even grieve her mother, Michaela is thrust into a strange house with a stepmom and three half-siblings--including her new sister Emery, who is less than thrilled at the prospect of sharing her room...especially when they both try out for the school musical and Emery's theater-star ex-boyfriend suddenly seems interested in Michaela. Can Michaela find a way to make a home with a family who didn't ask for her in the first place?
