It’s called ‘the Event’. An unimaginable cataclysm in the 23rd century shatters 600 years of the Earth’s timeline into jumbled fragments. Our world is gone: instantly replaced by a new one made of shattered remnants of the past, present and future, all existing alongside one another in a nightmare patchwork of different time ‘shards’ – some hundreds of miles long and others no more than a few feet across. San Diego native Amber Richardson is stranded on a tiny fragment of 21st century Britain surrounded by a Pleistocene wilderness. She crosses paths with Cam, a young warrior of a tribe from Roman Brittania, and together they struggle to survive – only to be imprisoned by Cromwellian soldiers.
