Sunny is the grandmaster’s daughter. She sweeps the floors, waters the plants, and practices with her nunchucks—sometimes she even makes mistakes. She teaches other young students how to kihap. When those kihaps grow loud enough to shake the mountains, she leads her friends in defending the dojang against magical creatures . . . or perhaps that’s just in their imaginations. It’s up to the reader to decide. Dan-ah Kim’s polished debut picture book puts a young girl in the center of an imaginative and accessible story about martial arts that will appeal to all readers. The straightforward text and vivid artwork celebrate teamwork, imagination, and perseverance. The Grandmaster’s Daughter is an irresistible read-aloud that also provides a subtle introduction to the five tenets of tae kwon do.
