Full Moon Bloom

As long and Luna can remember, it's just been her and her brother. They had a simple life as orphans so why did it look like her brother was always paranoid? He is 10 years older and all she has ever known. One day as her and her brother had just escaped from Lady Katherine and her crew after being on their vessel for 8 years, they come across a young boy in need of help. He has the same look as her brother, haunted and paranoid.
