Mercury

After a lowly software tester named Suzy Cilbrith uncovers evidence of a vast government conspiracy, she turns to a fringe reporter named Eddie Pratt for help. Far from dismissing her wild claims, Eddie reveals that things are even worse than they appear: the US government has been infiltrated by angels, who are attempting to bring about Heaven on Earth - no matter the cost.

Four years after the destruction of the planeport, Earth remains cut off from Heaven. The angels and demons are in disarray, lacking direction and leadership. Someone has to step up and take control, and that person is...Mercury? But when the demoness Tiamat finds out about Mercury's plan to reestablish contact with heaven, all hell breaks loose. Mercury finds himself at the center of a plot to rewrite Earth's history, and the only way to stop it is to travel back in time to prevent the plot from coming to fruition.
