The Elvish War

This is my first novel. If you have any complaints please tell me. This is based off a world I created in a dungeons and dragons game I dmed. Erwin is a psychopath. He has planned on killing his sister for 6 years after the death of his mother. After his one ambition in completed. He plans on killing himself. 8 years later he finds that he has been reborn and that his life is in danger. The war of the elves is about to begin. Just how will Erwin fit into all this? "What's up with that shadowy figure on my ceiling." "WTF why are the bullets not doing anything!!" "Was that a dream?" "Well that wasn't how she was supposed to die" "Wait was I really reborn?" "Why didn't I know anything for the past 8 years?"
