Abi and her beloved Grandad tell each other stories as they enjoy half term together on his allotment. They play games and sing songs as they work among the beautiful flowers and tasty vegetables. As they plant seeds – and memories -they share secrets and develop a bond that nothing can break. Ten-year-old Abi thinks Grandad is as smart and mischievous as wily Anansi; part human, part spider and the subject of many West African and Caribbean folk stories. She gives him the nickname Grandad Anansi. But as they romp amongst the rhubarb, okra and cauliflowers, Abi suspects crafty Grandad is hiding something from her. Can Grandad find a way to tell Abi about his plans to return to his Jamaican homeland?
