"Stealing a Starship" by Barton Paul Levenson has atypical characters and fully-fleshed out world-building. The characters are not stereotypical SF characters. It also involves stealing a starship--as you may have guessed. But the plot does not go the way you might expect.
Yes, I realize I'm being vague--but I don't want to spoil the story for you! Be sure to check it out on Nov 30!
Fun fact: this is not the first time we've published work by Mr. Levenson. If you're impatient, you can check out his "The Boogie-Woogie, Time-Traveling, Cyborg Blues", or his "Khuminay and the Axe-Wielding Psycho".
"Chasing Frisbees" by Derrick Boden has a particularly powerful and emotional character arc. It has fully-fleshed out world-building. It also has frisbee-chasing--as you may have guessed. But the plot does not go the way you might expect. And the unexpectedness is different from the unexpectedness mentioned above.
Furthermore, the 'big picture' of this story is a great metaphor for some other stuff...
Again, sorry for the vagueness, but it's unavoidable. :) Check out the story Nov 30!
Both of these stories are what I like to consider new classic SF. They have great, fun classic ideas--such as starships--but they also have an additional modern power and sensibility.
