"Eighteen-year-old Katie Price has a rare disease that makes exposure even to the smallest amount of sunlight deadly. Confined to her house during the day, she is limited to the company of her widowed father and her best (okay, only) friend. It isn't until after nightfall that Katie's world opens up, when she takes her guitar to the local train station and plays for the people coming and going. Charlie Reed is a former all-star athlete at a crossroads in his life - and the boy Katie has secretly admired from afar for years. When he happens upon her playing guitar one night, fate intervenes and the two embark on a star-crossed romance. As they challenge each other to chase their dreams and fall in love under the summer night sky, Katie and Charlie form a bond strong enough to change them - and everyone around them - forever." -- (Source of summary not specified)
