Its called ``the Event.`` An unimaginable cataclysm in the 23rd century shatters 600 years of the Earths 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. One of their captives is a man who Amber calls ``Merlin, and who claims to be the 23rd century scientist responsible for the Event. Together they must escape and locate Merlins ship before the damage to the timeline is irreparable.
