A young girl's wish is granted when a new sister arrives. While the baby can't do much, over time the big and little siblings become inseparable, playing and dancing, imagining and laughing. By each other's sides, they are smarter, kinder, and braver than they ever thought they could be. And they are forever sisters first. This exquisite celebration of the bond between sisters is inspired by the spirited childhood of Jenna Bush Hager and Barbara Pierce Bush, authors of the #1 bestseller .
