His fate was his own and his freedom hard-earned, having nothing to live for but the hunt and his perfect record. Until he received a distress call that changed his bleak existence. “Please, oh god, please. Is anybody out there? This is Norah Lee, a scientist of Earth. I-I don’t know what to do. I think everybody...everyone is dead. Please if you hear this, please help us. I can hear them outside. They’re coming… I don’t want to die.” Warning: mature readers only, explicit sex scenes, horror elements
