One true wish
(Book)

"Phoebe is a wish-granting fairy who doesn’t believe in children. Birdie, Gem, and Van are sixth graders who don’t believe in fairies. But deep down, each of them has a wish. Birdie and Gem have been best friends forever, but now things are changing, and Birdie doesn’t know why. Birdie feels left behind, while Gem feels she’s growing up too fast and no one understands what it’s like. Van is lonely, far from their friends in Ireland who never thought that being nonbinary was such a big deal. When Phoebe crash-lands in the woods nearby, the three kids must race against the clock to restore the fairy’s powers and get her back home. They’ll have to summon a new kind of magic to save Phoebe and their friendships—the magic of their deepest, truest wishes." --publisher's website
