My 7th short story was "The Orphan Hunter”, published in Aphelion in August 2017.
The genesis of the idea comes from the my participation in the newspaper business, which uses vending machines. Over the years I've noticed that when newspapers - as well as other businesses - go under, they seldom if ever retrieve their vending machines from storefronts and such. They usually abandon them there. Eventually someone will haul them off for scrap.
I thought, what if someone uses a pile of abandoned or junked vending machines to hide something... unusual?
