A dark fairy tale.
When she was young, she dreamed of the things every good little girl was supposed to want. A castle somewhere far away, where she could sit in the highest tower and wait for her true love to rescue her from the loneliness. Surely, she thought, it would all end with a kiss and a happily ever after.
As she grew older, she learned about reality. Reality was controlled by destiny, and destiny could be cruel and unrelenting. And sometimes the fair maiden was full of sin, and the knight in shining armor powerless against that which was foreordained.
Now, as she feels the pull of cold steel through her body and hears the sound of waves crashing in her ears, she thinks that maybe this could be some sort of strange fairy tale after all.
And isn't it a lovely twist, the princess choosing to save the prince?
