write a sci-fi novel

I’m currently working on a (very amateurish) novel titled Fringe. It’s about a group of people living in the Oort cloud of this solar system. They are at war with the people of the inner solar system. The main character is genetically engineered cyborg soldier. He starts off as a godless killing machine. But something about earth changes him. It touches something in his soul and makes him human. Well almost anyways.
