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 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.
A group of heroes forms: San Diego native Amber Richardson, Cam - a young warrior from Roman Brittania, Simon - a Teddy Boy from the 1950s, Phineas Van Seldoot - a supercilious Victorian gentleman, Blake - a soldier from World War II, an 1880's reporter named Nelly Bly, and "Merlin, and who claims to be the 23rd century scientist responsible for the Event. Aboard Merlin's ship they must return to his lab and repair the damage before it is irreparable. But when a Merlin doppelganger appears, they learn that not everyone may be who he seems to be. Allies may turn out to be deadly enemies.
