For thousands of years, humans dominated the Earth, coexisting with animals of the wild, testing ways to improve the planet they live on. But one experiment went out of control, spreading a contagious disease that affected the heart, and released a monster more complicated than anything Earth has ever seen, and its only intent is kill. It was a "survival of the fittest" kind of thing, and after only a few centuries, the last female was lost. The people became desperate, and invented a machine to produce the next generation. A thousand years later, number 573927 was born. It was supposed to be like all the others, male, but an unbelievable miracle happened. A female was born. Not one man wouldn't cut through an entire population to have her. But the question remains. Will this one female be an exception to the virus? Or will she fall to her death like all the rest?
