A lifetime as a lab rat, or forever on the run? For Michaela it's not a hard decision. Not many people can say their entire existence has been one big lab experiment: poked and prodded by scientists, genetically modified to be the best and endure the worst, subjected to daily tests and trials that would kill a normal human. All Michaela wants is her own life. When the chance to escape finally comes, Michaela and her sister run, taking their friends with them. But they aren't the only ones to free themselves from those labs. Following close behind are another breed of creature, one that doesn't know the difference between right and wrong, who exist only to feed their own hunger. The creatures are the least of her problems. As the world begins to fall apart around them, Michaela finds she could lose the very thing she holds dearest.
