41 Days: Apocalypse Underground

After the nukes fall,
In a secret biohazard facility, survival may be possible...
Until a knock comes at the door.

In a research facility hidden deep in the Maine woods, Jenn and her fellow scientists have been trying to prepare for a possible bioterror attack. But that's not how the end comes. It comes in blooms of mushroom clouds covering the globe.

With eleven people, plenty of water, and some food, they may be able to survive for eight weeks, perhaps just long enough to survive the worst of the fallout.

But the people inside unravel quickly. And things go from bad to worse when fists pound on the outer door.
