Book Review 2-5

I read the book "DEAD MAN'S ISLAND". I will tell the story.
Carol Sanders lived in Hong Kong with her family when she was younger. She was a fan of Jake Ross who was a pop musician, but he died in a car accident. Unfortunately, her father also died in a plane crash. She cried for weeks and spent many days alone in her room. After his death, she stopped doing her work at the college. She began to go out with dangerous friends. However, she and her mother decided to go back to England. A month later, they came back to England and then she found her mother's job in the newspaper. It was to work as a secretary in a private island in Scotland. They met Greta Ross who asked for a employee at expensive hotel. Greta Ross told Carol's mother to be her husband's secretary. At last they went to Scotland with Greta Ross, first by plane and then by train. After the train, they went on Mr Ross's boat which them out to the island. The boatman was a young man whose name was Tony. When they arrived on the island, they met Mrs Duncan who was the housekeeper and Tony's mother. Her husband also worked there as a gardener. That evening, they had dinner with Mr and Mrs Duncan and Tony in the big kitchen. Greta Ross took them to Mr Ross's office and they met him. He was a young man, but he had a moustache, short dark hair and he wore glasses. Carol studied farm at her college, so he asked her to help other workers and allowed her to ride a horse Smoke. She worked in the garden for the first two day. It was fine for her. When she took photos of the house, Mr Ross deprived her of her firm. She began to hate Mr Ross. About a week later, she found a locked room. When she opened the door, Greta Ross saw her and looked angry. She said to her that the room was private. Two days later there was a storm in the middle of night. She was hot and couldn't sleep. She found one window had a light in it. She went there and it was the locked room. She witnessed Mr Ross got out the room and locked the door of the room carefully. He did not put the key in his pocket, but hid it in the plant pot next to the door. The next day, Carol went into the room. There she looked at the dead Jake Rosso's picture and then she found Mr Ross's secret. She realized that Mr Ross was Jake Ross who had died. She blamed him for his secret . At last, he told her about his secrets all. At first, he said that the other people on that island were his family. When he was a famous pop singer, he killed one girl in a car accident. After that, he wanted to die, but he couldn't do. He faked the car crash and then everybody thought he was killed in the car crash. He changed his looks and began to live that island with his family alone. Carol promised to keep his secrets and she went back to England with her mother.
This book was higher level than before. Surely, it was a little longer, but grammars were not so difficult. However, this story was boring and too long for me. Anyway, I will keep high level books like this.
