Imagine you’ve just been told you’re the most insignificant person who’s ever lived. A nobody. Somebody less important to the world than certain types of mushroom. Not very nice, is it? That’s exactly what happens to Geoffrey Stamp after a man from the year 3050 asks him to become a “Time Rep” – a tour guide for the 21st Century, meeting people from the future who travel back through time for their vacations. You see, Time Reps need to be insignificant. Otherwise, when you go back in time and interfere with their destiny, the space-time continuum has a bit of a fit. And we wouldn’t want that. But when Geoffrey uncovers a conspiracy to change the course of history, he is sent on a mind-bending adventure through time and space involving an imaginary lake, a talking seagull, dinosaurs, aliens, the Great Fire of London, and the discovery that he might not be as insignificant as people thought…

Imagine you’ve just discovered you’re the most significant person who’s ever lived. A hero. You saved the world from an alien invasion. If it wasn’t for you, everyone would be dead. Sounds pretty good, doesn’t it? That’s exactly what happens to Geoffrey Stamp, but there’s just one problem—he can’t tell anyone. You see, Geoffrey is a Time Rep—a tour guide for the 21st century, meeting people from the future who travel back in time for their vacation. Everything he does needs to be kept a secret from the people in his own time, otherwise he risks changing the course of history. And that caused enough trouble in the last book. But now a new company called Continuum is offering holidays to the past, and they allow people to go back and change whatever they like. For Geoffrey, this sounds like a dream come true, until a future version of himself appears out of nowhere with no memory, a bullet in his back, and a Continuum business card in his pocket. Geoffrey soon finds himself in a race to solve his own attempted murder, but begins to wonder if his investigation is the very thing that nearly got him killed. What is the truth behind Continuum, and after he saved the planet, why would anyone want him dead?

Imagine you’ve just done something that might have broken time. Quite significantly. Cause and effect are no longer on speaking terms, sequences of events aren’t flowing the way they should, and reality has become a warped and fragmented mess. sound Doesn’t ideal, it does? That’s exactly what happens when Geoffrey Stamp reveals to his friend Zoë that he’s a Time Rep—a tour guide for people from the future who travel to the past for their vacation. Everything he does was supposed to be kept a secret from the people in his own time (for reasons quite extensively explored in the previous two books), until Geoff decides he’s fed up with doing what he’s told. It’s just a shame that time has now decided to misbehave too. Faced with navigating a corrupted reality of splintering timelines, Geoff and Zoë must work together to make sense of what has happened, without losing their minds. But as the past descends into a blur of conflicting recollections and a disturbing future seems unavoidable, it appears other forces might be at play, exploiting the fractures in time for their own sinister purposes. Why has time broken? And if cause no longer produces the right effect, how can Zoë and Geoff possibly fix it?
