trapped

At 15 years old, a girl has lived in a bunker for her entire life. She resides with another girl, Lacy. The bunker is the only life they have ever known. There is one other person who lives in the bunker, he gives them food, he keeps them safe from the dangers of the outside world, and they know they can trust him. They call him Sin, but they don't know what his name really is. They don't think they will ever know. He never tells them anything. In the bunker the only source of entertainment is reading the same picture book everyday. The book houses pictures of mountains, rivers, and flowers. What are these strange objects? Will Sin ever tell them something? Will he tell them what these 'mountains' are? They don't know. But will they ever know?
