Koran: a Hired Sword

This is a book I started for my creative writing class in college... I'm working on finishing it but wanted to try out this site and get some feedback! This story is about a young boy named Koran who loses his family and is hired as a bodyguard (called a "hired sword" in the book) by a man with a big belly and a big mouth. They spend the night in a town not far from the Castle, and Koran wakes up to the town under siege and must save himself and his companion. Koran's skills are put to the test both with a sword and with talking to a girl, and he learns a horrible truth that starts him on his journey. Let me know what you think!
