Let me tell you about the day my life ended. I remember it as if it was yesterday which, maybe, it was. Or perhaps it will be tomorrow. I lose track. After all, it was a long time ago. At first, Jamie Grant thinks people are just ignoring him. His teacher, his classmates, even his own mother! Everyone—apart from his little sister, Ellie—is suddenly acting as if he's not around. He's fallen off the register at school, people don't reply to his questions, and he's not even showing up in old family photos. Creepy or what? Eventually, with the help of the friendly but mysterious Anna, he comes to realize that he doesn't exist—and he never has. He's fallen through a time break and is living in a parallel world in which he was never born. What's more, Jamie discovers that although he is outside time, he has the power to control it—and so he and Anna are employed as Time Runners to fix the rips in time. But they must work against the sinister Darkling Midnight, who is intent on causing chaos throughout history, to prevent time from falling apart.
