From Newbery Medalist Meg Medina comes the bittersweet story of two girls who will always be each other's número uno, even though one is moving away. A big truck with its mouth wide open is parked at the curb, ready to gobble up Evelyn's mirror with the stickers around the edge . . . and the sofa that we bounce on to get to the moon. Evelyn Del Rey is Daniela's best friend. They do everything together and even live in twin apartments across the street from each other: Daniela with her mami and hamster, and Evelyn with her mami, papi, and cat. But not after today—not after Evelyn moves away. Until then, the girls play amid the moving boxes until it's time to say goodbye, making promises to keep in touch, because they know that their friendship will always be special. The tenderness of Meg Medina's beautifully written story about friendship and change is balanced by Sonia Sánchez's colorful and vibrant depictions of the girls' urban neighborhood.
