I liked this a lot. It grabbed my attention at the beginning and the point of the story remained elusive to the end, where it was a nice rush. I liked it also because it turns such a crappy thing into a silver lining.
The point of view shift wasn’t apparent to me where Julia saw it. I guess I figured Martin was close enough to hear her whisper. But later on, she goes to her car to find paper, and finds a pen but no paper. Because Martin wasn’t there to see that, it didn’t feel like part of the story.
