Idea 1
Luna Dethpur (21) has been feeling hopeless for her life for awhile. Don't ask why, because it'll take days or even months if you want to know the reasons.
Luna's so fed up with her life, that she even feels like dying. The only reason that she never tried to commit a suicide is that she wants to know more about the world, but the more she knows the more despairing she gets.
One day, all of a sudden she came up with the thought that if she could trade her own life for her brother's. Her elder brother, Dreatcher, who died years ago, was actually living the kind of life that seems perfect to her. He had a well-planned, and meaningful life, and just being with him almost made Luna's life so meaningful.
