Acheron

Captain Nate Leathers thought being a soldier on the frontlines in Iraq was hard enough. And when his convoy is attacked and he's thrown in a dungeon by insurgents, he can't imagine things can get any worse. But then the world is turned upside down. When he escapes, Leathers finds the city of Basra shrouded in green mist and under siege from nightmare creatures far more horrific than any terrorist. Walking corpses. Tentacled beasts. Giant slithering things. Ancient creatures risen from the depths. Alone in the city Leathers will have to draw on all his training to survive, let alone stop the mist from spreading. Monsters beyond imagination are closing in ... and some of them are human.
