Book about 3 girls in Africa

[christine19]

Hi, I read this book about 2013.the book starts out the 3 girls are all at their school in their school uniforms and one of the Moms is late to collect them. I think it took place in the 60’s/70’s andout the white friends. One is English and her father is a diplomat, one is Irish and her parents are doctors and the other is Africaans and her parents own a ranch/estate, she has a brother and he plays into the story kore as the girls age. They’re all living South Africa I think, I know one of the girls moves away to Rhodesia, but moves back. The Irish one goes back to Ireland and studied medicine, the English one goes back to England and becomes a model or something like that. They all come back to the ranch in Africa and that’s when the bad things start, the English one is then scarred. The brother and the Irish one get together towards the end.
