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, with a leopard-print case to match. When her distracted dad and her long-distance mom (temporarily in Myanmar taking care of Mya's grandmother) both say no, no way, and possibly never, Mya launches a campaign to prove herself reliable and deserving. She advertises her babysitting services, takes on more responsibility around the house, and attempts to supervise her sister's skateboarding lessons. Her efforts leave her ego bruised and the kitchen slightly scorched. She's no closer to touch-screen victory, let alone the Nobel Peace Prize she deserves. But all that changes after an accident leaves Mya to take charge-an experience which helps her realize how much she's grown, with or without access to proper communications.
