From the critically acclaimed, award-winning creators of Ocean Meets Sky and The Night Gardener comes a whimsical and sweet tale of a young girl who cares for her pet cloud as it grows. It’s a little out of fashion to buy a pet cloud, but Lizzy doesn’t mind. She’s not looking for a big one or a fancy one, just one that’s right for her. And she finds it in Milo. Soon, she’s taking Milo out on walks with her family, watering Milo right on schedule, and seeing Milo grow and grow. But what happens when her pet cloud gets too big for Lizzy to handle?
