Dante's Plague

First, it slips into your system with ease and ravages you from within, undetected. Then you begin to experience symptoms and, ever so slowly, lose your mind. Finally, it has free reign over you and mutates your broken shell to sustain itself, killing anyone in its vicinity for nourishment. They are not zombies or vampires or gargoyles or any of the twisted figments of our imagination we always feared would come to life; the hosts become something much more.... demented. They are Dante's, the demonic, primal offspring of the disease and man. These beasts are no longer considered human, and are slaughtered on sight, whether they have been transformed or freshly infected.
This Plague has humanity running in terror and the infected scrambling for death. But it's okay, because I already have it. My name is Cassidy, Cassie if you like, and you are currently reading what has either become my last years of madness put to paper, or the story of how Dante's Plague was cured, of how I impossibly survived this hell. You see, I have found someone impossible, someone immune, and they are the indefinite cure to my madness, the world's madness. With salvation in reach we journey further into insanity and race to outrun the disease biting at my heels. It all starts surrounded by the glaring white walls of a hospital and is followed in the furious glint of the sun beating relentlessly down on a broken survivor.
