Maybe I'm Dreaming: An Owl City Fanfic

Hadley has always admired Adam Young. It's always been her dream to meet him. The fact that they had the same last name had nothing to do with it. It was him and his music. When she visits Owatonna for a few weeks, she finally gets to meet him. But something is unearthed during that time--Hadley and Adam are siblings... and Adam knew of his sister all along. Both of them have the same question running through their minds. Is this a dream?
