Dark Inside (Dark Inside, #1)

Since the beginning of mankind, civilizations have fallen: the Romans, the Greeks, the Aztecs...and now us. Huge earthquakes rock the world. Cities are destroyed. But something even more awful is happening: An ancient evil has been unleashed, and it's turning everyday people into hunters, killers, and crazies. This is the world Mason, Aries, Clementine, and Michael are living in--or rather, trying to survive. Each is fleeing unspeakable horror, from murderous chaos to brutal natural disasters, and each is traveling the same road in a world gone mad. Amid the throes of the apocalypse and clinging to love and meaning wherever it can be found, these four teens are on a journey into the heart of darkness--and to find each other and a place of safety.
