The Nephilim Series - The exterminator

This first person story is about a young fourteen year old boy who is forced to kill for the government to keep his family safe and fed. In the world there are terrible leaders and almost every person is either a warrior or a peasant. He is forced to be trained as an assassin and kill anyone who the governor known as Drogan tells him too. If you're on his list, you won't live to tell the tale of him. No one expects a kid to be a murderer so it's perfect, until he's caught. Will he get killed or something worse...?
