John and Sarah's Dad has had a bike accident. He isn't too badly hurt, but has hit his head and will have to stay in hospital. They want to visit him and take him sweets and flowers. The only problem is they don't have any money. So they decide to earn some by weeding gardens, doing washing up, fetching people's shopping. Rosie has her own idea of a job she's going to do and for once she won't tell anybody her secret.
In the meantime they help Mum out and their jobs help them see how well they can do things for her. But will they earn enough money, and what has little Rosie been up to?
'The Fabulous Four' is a series of books with a moral edge. They centre around John, Sarah, Sam and Rosie, four cousins who spend nearly all their time together.
