A Dance among the Fair Folk

Evelyn has had dreams and visions since she was a young girl playing in her grandmother's backyard. On her therapist's advise, Evy decided to capitalize on it at the ripe age of 17.
Now at 30, she's an accomplished author, but is now having a new dream from the night before when her friends surprised her for her birthday while on tour for her latest release. While out at a fantasy ball she believes that the sudden appearence of someone the spitting image of one of her characters seems to be either a crazed fan or glorious hallucination.
Maybe it was all in her head, but she still enjoyed it. Until she was met with proof that she wasn't actually crazy to begin with.
