Orbit (John Nance)

The lucky man who wins a lottery to ride along on a four-day low-orbit commercial space flight deems it not so lucky when a micrometeorite kills the flight commander and leaves him trapped in orbit with no communications with the ground and no chance of returning. He begins recording his thoughts on a laptop, expecting they might be found decades later; he doesn't know what he types is being picked up in real-time and broadcast around the world. Humanity gets caught up in his story, and it has powerful influences on everyone. The end is rather unconvincing, but I found the story gripping and struggled with him as he tried to figure out how to live his last days.
