Dominic Gorden's life suddenly takes a shocking turn. Whilst Painting at his Grandad's house he discovers an old family photo album, with pictures of him inside. Thats what he thinks, until he turns the last page and finds himself 5 years older than he acctually is. Then the word 'Brother' flickers across his mind. And his life is changed forever.
A few days later he is on a train heading to Cambridge Univercity, where he has found out it is where his brother studied and died. There he meets his brother's best friend, Giles and his wife, Becky, who was once his brother (also called Domonic's) girlfriend. Unable to come to terms with himself, he meets his brothers Tutor, Professer Holt. She is the worlds greatest scientist, and so was his brother. Imogen (Professer Holt) lets him come back to her house with her and her husband and lets him selep there the night.
Later on, as Dominic gets up to get a glass of water, he overhears them talking. 'Why did your baby have to turn up now??' That solved it. Imogen was his real Mum. It did make sense... she had been on holiday with his parents just before Dominic was born.... With a desperate surge he called Giles and he met him at Cambridge Uni. But then, Imogen turns up and when Dom questions her about the baby, the real truth comes out....
His Mum and Dad could not come to terms with their perfect son's death. They had employed Imogen to clone the dead Dominic to make the Dominic that lives today. Basiccly, he is living inside his brothers dead body. He was only made to keep the memorys of the long dead Nick (his brothers nick-name) alive. Imogen knows that if this comes out in the press she will be executed. Felling lost and emotionless, Dom plans to go up to Scotland with Giles and Becky. Suddenly, out of the blue, his evil father turns up and tells him he's taking him to Australia. In one last frantic surge he runs away again up to Scotland to meet Giles and Becky, who only want whats best for him.
After a couple of weeks living with Baecky and Giles, Dom gets a mysterious call from Imogen, telling him that he is in danger and he needs to meet her urgently. As Dom heads out to find her, he is cornered by a journalist, who knew his brother Nick and has suspected something fishey. As Dom trys to hide on a cliff ledge, the reporter follows him and threatens to tell the newspaper about this. As Dom thinks he is defeated, Imogen turns up and snatches the journalist's phone away from her. They have a shouting row, and, at the end of it, as they are on the ledge of a mountain, they accidently thow themselves to their death. Dom feels so guilty that, he thinks he ought to let the police know the hole story. As the last lines of the book read: 'My experiences are all Unique and Unrepeatable, Like cloud-shadows on mountains or flames in a fire.
