The Pages of Time by Damian Knight

Sam Rayner thinks he is an ordinary teenager. But when his family’s flight is brought down in an act of terrorism, he suffers a brain injury that leaves him in a coma.

After waking in hospital, Sam begins to experience seizures that distort time and transport him into the body of his past or future self. With no way of controlling when they happen or where they take him, these episodes seem more like a disability than anything useful. That is until Sam finds himself flung several hours ahead, where he overhears a news report about another terrorist attack.

Could this information hold the key to preventing the atrocity before it takes place? Can Sam find a way to save his family from violent deaths that are already in the past, defeat the sinister forces that wish to use his powers for their own ends, and maybe also win the girl he loves…by turning the pages of time?
