Twelve-year-old Lizzie Chu has lived with her wai gong (grandfather) in Glasgow since her parents died when she was a baby. But Wai Gong has been acting different lately. He spends a lot of time talking to his Guan Yin statue—the Chinese goddess of compassion, kindness, and mercy—at his altar and seems to be becoming more forgetful. Even the shared passion he and Lizzie have for their favorite show, , seems to be tailing off. Then one day Lizzie’s friend Chi visits dressed as Princess Leia for Comic Con, and Wai Gong mistakes her for Guan Yin. He’s delighted—and Lizzie gets an idea. She and Chi (dressed as the goddess) can take Wai Gong to a ballroom dance at the Tower Ballroom, where he’d always dreamed of going with his late wife. If only she can get her granddad there, she thinks, he’ll find some peace, and perhaps things will be OK at home again. After all, one of the myths around Guan Yin is that she brings order and harmony, so it’s got to work out—right?
