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.
Only one angel knows the secret to exposing the cabal: the rogue cherub known as Mercury. But when Mercury learns who is behind the cabal, he realizes he's going to need a lot of help. Old enemies become allies, old friends become bitter enemies, and as competing plots for world domination unfold, it isn't always clear which is which.
