Charlie Morningstar has always been a curious girl with an active imagination unlike any other kid. Unfortunately, a creative mind such as hers comes with its downsides, such as lack of common sense and naivety that would often get her into strange predicaments. Luckily she has her guardian, Alastor, who has sworn to always protect her from harm for as long as she lives, but in exchange she must give her soul to him on the night of her 18th birthday to ensure they will be tied together for eternity. As she grows up, she begins to feel stronger feelings towards her protector. But the mysterious "friend" of hers raises concerns for her parents, who start to wonder if this imaginary friend she's made up is more than what she says... ((Human AU! Rated M for mature themes.
