To read the book "Hidden Valley Road: Despair and Hope of a Schizophrenic Family", we must first know some information about the Calvin family. Father Donne is an officer in the United States Air Force Academy. He has a doctorate in political science and loves eagle training. His career flourished after the war. During this period, he served as the intelligence officer of the president of the United States, and was later transferred to the North American Air Defense Command as the intelligence staff. Mom Mimi comes from an upper-class family in Texas. She not only went to college, but also kept close contact with celebrities from all walks of life. Her mother is also a friend of oil tycoons and business tycoons. Donne and Mimi met at the age of 13 and fell in love at first sight. After the outbreak of World War II, Donne was about to be sent to the Pacific battlefield to get married. After twenty years of marriage, Mimi has always given birth to 12 children, 10 boys, and two youngest daughters, Margaret and Mary.

12 children, the top ten are boys, and six boys have suffered from mental illness. Members of this family have experienced violence, suicide, sexual assault and mutual harm. Illness will expose the fragility and darkness of human nature, and also show the tenacity and greatness of the family. Margaret and Mary are the youngest daughters in the book. When they were little girls, they were sexually assaulted by their sick brother. Their parents adopted a policy of indifference and avoidance on this issue. Mary tried to burn Donald. But on the other hand, it shows the greatness of family. When Mary grew up, she spared no effort to take care of her sick brother.

This book tries to tell us that those who unfortunately suffer from this recessive disease should not be monsters isolated and abandoned by society, but people who are suffering great misfortune and need to be saved urgently.
