There's a talent show coming up, and middle-school kid Parker has no idea what her talents are. Is everybody great at something but her? But then she runs into a mysterious person who looks exactly like her, and hands her a phone. Not an ordinary phone... a phone that can call parallel universes! Now Parker can summon alternate Parkers with all the skills she wishes she had. She'll dominate the talent show, and never have to deal with problems again! But all that messing with the multiverse comes with consequences, and soon Parker finds herself racing to save the entire multiverse from total destruction.
