From a #1 New York Times–bestselling author, a guardian angel lends friendship, support and magic to a girl struggling with her brother’s illness.

At a first glance, Aria seems like your average twelve-year-old girl. She has coppery hair, colored shoelaces, and a passion for cupcakes. But there’s more to Aria than meets the eye. She can dream things into existence, use her own shadow like a door, and change the world in small, important ways. Aria is a guardian angel. She’s been sent here to earn her wings. But to do that, she’ll have to help three different girls.

Aria’s first mission is Gabby Torres. Gabby’s always been quiet, but ever since her brother got sick, she’s barely said a word. When a new school offers her a fresh start, Gabby wants badly to be someone new, but she quickly learns it’s hard to make friends while keeping half her life a secret.

And then Aria shows up. Aria, who knows exactly what to say and do to make Gabby feel better. Will she be able to help Gabby find her voice? And will Gabby still trust Aria when she finds out exactly what she is?
