And it isn’t even the strangest thing to happen to him that week. Nick and his Dungeons & Dragons-playing friends are used to living in their imaginations. But when a new girl, Mia, joins the group and reality becomes weirder than the fantasy world they visit in their weekly games, none of them are prepared for what comes next. A strange—yet curiously familiar—man is following Nick, with abilities that just shouldn’t exist. And this man bears a cryptic message: Mia’s in grave danger, though she doesn’t know it yet. She needs Nick’s help—now. He finds himself in a race against time to unravel an impossible mystery and save the girl. And all that stands in his way is a probably terminal disease, a knife-wielding maniac and the laws of physics. Challenge accepted. less

One choice. Two possible timelines. And a world hanging in the balance. It’s the summer of 1986 and reluctant prodigy Nick Hayes is a student at Cambridge University, working with world-renowned mathematician Professor Halligan. He just wants to be a regular student, but regular isn’t really an option for a boy-genius cancer survivor who’s already dabbled in time travel... moreOne choice. Two possible timelines. And a world hanging in the balance. It’s the summer of 1986 and reluctant prodigy Nick Hayes is a student at Cambridge University, working with world-renowned mathematician Professor Halligan. He just wants to be a regular student, but regular isn’t really an option for a boy-genius cancer survivor who’s already dabbled in time travel. When he crosses paths with a mysterious yet curiously familiar girl, Nick discovers that creases have appeared in the fabric of time, and that he is at the centre of the disruption. Only Nick can resolve this time paradox before the damage becomes catastrophic for both him and the future of the world. Time is running out—literally. Wrapped up with him in this potentially apocalyptic scenario are his ex-girlfriend, Mia, and fellow student Helen. Facing the world-ending chaos of a split in time, Nick must act fast and make the choice of a lifetime—or lifetimes. Game on. less
