Eleven-year-old Polly Peabody knows her family's world-famous rhubarb farm is magical. The plants taste like chocolate, jewels appear in the soil, bugs talk to her, and her best friend is a rhubarb plant named Harry. But the most magical thing is that every single Monday, at exactly 1:00, it rains. Until the Monday when the rain just stops. Now it's up to Polly to figure out why - and whether her brother's mysterious illness and her glamorous aunt Edith's sudden desire to sell the farm have anything to do with it. Most of all, Polly has to make it start raining again before it's too late. Her brother's life, the plants' survival, and her family's future all depend on it.

Kathleen Van Cleve has woven an unforgettable comingof- age tale with all the heart and wonder of a Roald Dahl novel.
