Mya Parsons runs her school's social justice club with her best friend, Cleo. Her lifelong desire is to work for the United Nations and change the world, and then bask in all the ensuing adulation. Her more immediate desire is to get a phone, preferably one like Cleo's. When her distracted dad and her long-distance mom both say no, no way, and possibly never, Mya launches a campaign to prove herself reliable and deserving. Her efforts leave her ego bruised, but after an accident leaves Mya to take charge she realises how much she's grown, with or without access to proper communications.
