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 Zo� 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 Zo� 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 Zo� and Geoff possibly fix it?
