One of my favourite series of books is The Casson family stories. They are about the casson children, Cadmium, (Caddy) Saffron (Saffy) Indigo, Rose, and their parents, (who are both artists,) Eve and Bill. The books are Saffy's Angel, Indigo's Star, Permanent Rose, Caddy ever after, Forever Rose and Caddy's World.
The children are all named after colours. Below is information about the first book, Saffy's Angel.
Saffy's Angel is about when saffron casson finds out that she is adopted. Five years later, when her grandfather dies, he leaves her a stone Angel that she used to play with in her garden. Nobody knows where that garden is, until saffron realises that it is in her old home, in sienna, italy. She stows away in her friend, sarah's car, when sarah and her family go on holiday to italy, the same place she had last seen when she was three years old. She is determined to find her angel, whatever it takes.
It is a brilliant book which I really loved, and I hope you will enjoy it as much as I did.
