The 5ifth Cycle - D L Ryder - Bog

It happened gradually at first. That's how it always happens, these bad, awful things... It slips past you, unnoticed. You see it out of the corner of your eye. In the back of your mind, you wonder what it was. Before the front of your mind catches on, it's too late.
The 5ifth Cycle is a gripping biotech/horror thriller about a virus out of control and unleashed upon a tiny, isolated town. When the virus escapes the confines of a remote bioengineering complex in Death Valley, the nearby town of Arroyo Caliente is quarantined with no warning, no explanation, and a rapidly-growing infected population.
With their town shut down and completely cut off, it is up to a select handful to escape the quarantine and, like rats in an experiment, venture back through the maze and infiltrate the source in order to save themselves.
The 5ifth Cycle is a complex, fast-moving story that flips the zombie plot on its ear by turning the improbable into the plausible. In the end, you're left with the uncomfortable feeling that it could happen.
