As described on the FCBD website,
Jerusalem lies in ruins, and the war humanity must fight in the wake of its destruction is like nothing anyone on Earth could have anticipated. When an alien race begins plucking swarms of people from everyday walks of life, they are told to brace themselves to fight in a battle to decide the fate of Earth.
