I will try to formulate it...
"The Silent Cry" is about two brothers: Mitsusaburo (Mitsu) and Takashi. Mitsu is a single-eyed young man: he lost his eye because of children who were playing in the street and throwing stones. The mother of these heroes always considered Takashi as a very beautiful boy and thought that he would score big successes; she was sure Mitsusaburo would depend on his brother because of it.
Mitsu has a wife. Her name is Natsu. Their son is very ill (if I don't make any mistake he is an imbecile), so, they left him in the clinic. They both suffer because of that and Natsu becomes an alcoholic.
Takashi is a weak person who wants to feel and to seem strong (it is my opinion). He lives in the world of his dreams.
The brothers' family had been one of the leading families in the village. Takashi is obsessed with the memory of their great-grandfather's younger brother, who had led a peasant revolt in 1860. Mitsusaburo remembers the affair differently, believing that the leader of the rebellion had betrayed his followers.
Takashi begins to organise the youths of the village into a group, beginning with football training on the same place where his ancestor was assembling his supporters. Mitsu notices that villagers become followers of his brother...and Natsu, too.
"The Sound of the Mountain" shows the Ogata family from the perspective of its aging patriarch, Shingo. Shingo has already begun to experience temporary lapses of memory, to recall strange and disturbing dreams upon waking, and occasionally to hear sounds heard by no one else, including the sound of mountain.
Shingo begins to observe more closely his relations with the other members of his family (his wife Yasuko, his son Shuichi, Shuichi's young wife Kikuko, and his daughter (Shuichi's sister) Fusako, who has left her husband and returned to her parents with her children).
He has never loved Yasuko: he admired her sister. This woman married another man who seemed very beautiful to Shingo. Later she suddenly died. Yasuko wanted to be with her sister's husband but he loved his dead wife.
Kikuko is very kind, sincere, Shingo adores her and watches with broken heart Shuichi, who is an unfaithful husband.
Oh, looks like I did it! I've given you the basic information about these books and I am waiting for your opinion!
