A bad day in Hell is better than crash-landing in the ZOO...

Especially if you wonder whether your helicopter pilot is certifiably insane.

The surge is hitting the world. Focused on containing an outbreak to save humanity, a helicopter goes down without anyone to rescue the survivors.

This was a civilian delivery, not a military foray, so the survivors have a snowball’s chance in hell of surviving.

Ava Martin, medical school dropout and government support staff, has just about the worst group of colleagues with whom to go into a dark alley at noon and make it out the other side. 

How is she going to deal with being dropped into a place heroes fear to tread?

The problem, one among many, is that the person she believes might be able to withstand the ZOO is either crazy like a fox...or bat-shit crazy.

The ZOO is making its move. Will those around the ZOO survive to hold it off, or is the world now a few short years of total destruction?
