Was it all just an accident?

AU! Serena was born flowing with fairy type pokémon blood. When Serena moves to Kalos with her mother she might just get to meet her father after all... but is he what she expected? Or is he something else? The young girl is tasked with going on a pokémon journey that may just have answers she was looking for... Not to mention the possibility of falling in love with a cheerful boy who always seems to be three steps ahead of her. As she embarks on a frivolous journey around the region she meets new people and makes new friends. Of course, She was never meant to meet them but was it all just an accident?
