The Hell of It by Peter Orullian
This was a free short story that I read on Tor.com. I didn't realize that they offered these shorts until I started seeing them in my Facebook feed. So, like a sci-fi junkie, I click each time I see one and read.
One thing that I love about these Tor shorts is the artwork for the cover image!
THE HELL OF IT starts out strong. The world building is pretty awesome and unique. A father and son struggling on the docks, a missing mother, a whole heck of hopefulness. It was the tragic ending that ruined it for me. If it had turned out differently I would have added another star, but the author broke my heart a bit.
