Nana speaks of astronomy often, telling fantastical tales from many moons ago, tales her granddaughter wonders at. Tonight, with hot chocolate and constellations for company, they wait. Moonbeams bounce off the crashing waves, and, at last, Nana's old friend appears in the sky: the Night Whale, swimming among the stars. Nana and the child climb onto the Night Whale's back, and she whisks them off--over twinkling cities, through the shimmering colors of the northern lights, and back again. But this is only the beginning of the journey for Nana. As she embraces her grandchild, she promises she will always be out there. Even when Nana and the Night Whale soar back toward the ether, leaving the child behind, she can still feel her grandmother's love and hear the Night Whale whispering, "Anything is possible." Debut author Bryher Mackenzie and illustrator Gillan Eilidh O'Mara craft a magical voyage through the heavens that reassures young readers that goodbye is not the end.
