Twelve-year-old Lizzie Chu lives in Glasgow with her grandad Wai Gong, and he's been acting a little strange lately. He is becoming forgetful, and spends a lot of time talking to his statue of Guan Yin - the Chinese goddess of compassion, kindness and mercy. Lizzie is worried about Wai Gong, but doesn't really know what to do to help him. She's already got a lot on her plate with caring for him, doing the shopping and everything else on top of schoolwork and the usual trials of being twelve! Then Lizzie comes up with a madcap plan. She's going to take Wai Gong on the trip of a lifetime, to Blackpool - to the Tower Ballroom, where he always longed to go, to dance with his late wife Grandma Kam. To rekindle that love for dancing and to see if Wai Gong can find his mojo again. The only problem is - just how on earth is she going to get him there? With a little help from her friends Chi and Tyler, some ingenious costumes and an older brother with a beat-up Mini, Lizzie might just make it - and maybe she will be able to help Wai Gong get better after all?
