From #1 New York Times bestselling author Victoria Schwab, three whimsical and enchanting novels about a quirky and clever guardian angel, and the girls she's sent to help, in one irresistible volume.

Aria Blue seems like an ordinary twelve-year-old. She loves music, and colorful shoelaces, and taste-testing various types of cookies. But there is much more to Aria than meets the eye. She can use her shadow like a door to travel from place to place. She can dream things into existence. And she can see when certain people need help.

Because Aria is a guardian angel. Her mission? To find and guide three different girls -- Gabby, Caroline, and Mikayla -- through their different problems. If she succeeds, Aria will earn her wings. But helping these girls is no easy feat, even for someone with magic powers. Things like friendship and family and well, life, are all a lot trickier than Aria might have guessed. Still, she's pretty sure she's up for the challenge . . .

Meet a magical girl like no other, from an author like no other, in this one-of-a-kind collection.
