Peak- end of book reaction

Peak, by Roland Smith, is a realistic (sort of ) fiction book about a kid who's parents are both experienced climbers, and his dad left him as a child to run expeditions on mountains like Everest. The book starts off with Peak,  the main character, climbing skyscrapers in New York because he wants to climb and the buildings are the tallest things around. On this one particular night when he is climbing the Wolworth building, he is caught by the police. After hearing about his climbs, a boy with no climbing experience tries to climb a building to be "cool" like Peak and falls to his death. Peak is arrested and put on trial just for climbing the building, but people are even more mad at him because of the other boy's death.
        The first twist in the plot comes when Peak's father, who has been out of Peaks life longer than he can remember, shows up to the trial. He offers to take Peak out of the country to keep the media away. He says that Peak is going to be going to an international school in Nepal, but he has other plans. When they arrive in Kathmandu, a city in Nepal, Josh (Peaks dad) tells Peak that the real plan is for Peak to climb mount Everest. If he does, he will be the youngest person ever to summit the mountain.
        Throughout Peak's training on the mountain, he starts to have mixed feelings about his dad. He thinks that his dad wants to have Peak break the record just to get publicity for his company. Also, he thinks about how his dad was never his father, he was never there throughout Peak's life, and Peak resents that.
         I think that Peak has good reason to be mad at his dad, but also in a way I think that Josh is sort of trying to make it up to Peak, he just doesn't know how to because he feels ashamed that he was never a good father.
