Yu-Rhee, a young Korean girl, wants to know how to tell time using a clock.

Her mother tells her a tale from her childhood based on the traditional Korean practice of timekeeping, where the 12 animals of the zodiac are assigned to 2-hour sections of the 24-hour clock. Told from the point of view of a mountain, the story follows a child as they climb the mountainside in search of a plant to heal their ailing mother. The climb is steep, the path wild and the way difficult. The mountain watches the child struggle and calls on the animals that live on the mountainside to help the child, but as sunlight turns to moonlight, each animal claims to be too busy. Ultimately, Once Upon an Hour is a story about determination and teamwork that shows young readers the importance of helping others.

Orca Book Publishers is pleased to offer Once Upon an Hour in two accessible editions. The audiobook features alternate text descriptions of images, including the cover. The epub edition of this title is fully accessible.
