"Beyond the Gate" by Terr Light appeared in Daily Science Fiction on January 15, 2013. "A retired old man tells his grandson a story about how humans sent all androids into space, and then suddenly has a feeling that the androids have returned."
Mr. Light's tale is worthy of a Twilight Zone episode complete with a twist ending that I never saw coming. In the author's note, he admits that the story once had a different ending. I must admit, I am curious about what it was. The ending as presented is perfect. 7 out of 7 rocket-dragons.
