HIgh Noon was about 3 half sisters who had to live a year on a ranch with the father. Only one of them could deal with the situation. It's was another of her stories filled with suspense and murder.
All of them need to learn to cope and solve all they're problems to go on with life. All the troubles help to bring them together and they learn to defend each other as a family.
It always reminds you how good your family life is after reading they're problems and seeing them working through them.
