Time shatters into shards of the past, present, and future. A group of survivors dodges threats from across history to locate the source and repair the damage before it's too late. IT'S CALLED "THE EVENT," AN UNIMAGINABLE CATACLYSM THAT SHATTERS 600 MILLION YEARS OF THE EARTH'S TIMELINE. Our world is gone, instantly replaced by a new one made of scattered remnants of the past, present, and future, dropped alongside one another in a patchwork of "shards". Monsters from Jurassic prehistory, ancient armies, and high-tech robots all coexist in this deadly post-apocalyptic landscape. A desperate group of survivors sets out to locate the source of the disaster. They include 21st century Californian Amber Richardson, Cam, a young Celtic warrior from Roman Britannia, Alex Brice, a policewoman from 1985, and Blake, a British soldier from World War II. With other refugees from across time, they must learn the truth behind the Event, if they are to survive.
