  Summary

  Simon is destined to die at the bottom of the ocean. Grace is destined to die in the emptiness of space.

  Destiny has a funny way of mixing things up.

  When Simon has just about given up, he finds a little Grace. Literally. How the hell did a pinky-sized human end up in his submarine? And what does it even matter, if they're about to run out of oxygen?
