The Bunker Vol. 4

As Grady Potts' political star rises, Daniel finally realizes what he must do to ensure he doesn't poison the world's population, and it isn't pretty.

Heidi is still imprisoned, but just like Billy, she's got an advocate on the outside. In this explosive final volume of the critically-acclaimed series, the fate of the world will be decided.
