Courtney Moore is the best gamer at the arcade. But she can't understand why there aren't more girl characters. When Courtney imagines her own video game, the hero is a girl who knows how to handle any situation. If only I was like that in real life, Courtney wishes. Her dad's moving for a job, so Courtney won't be living with him on the weekends anymore. That's causing a big problem with her stepsister, who doesn't like sharing a room with Courtney -- or her guinea pig. When her mom announces that she's running for mayor, Courtney's blended family has to learn to work together differently. It's a whole new game for Courtney, and she's figuring out the rules as she goes.
