In addition to the novel Semiosis and the upcoming sequel Interference, two short stories explore life on Pax.
“Cinderella Faraway” is set between chapters 1 and 2. Nicoletta and the other children wonder if their new life is really better than it would have been on Earth. Warning: this story is grim.
“Spiders” is set between chapters 3 and 4. Roland’s father takes him for a walk in the forest while he’s a young boy. This story, which features a lot of fun worldbuilding, was previously published in Asimov’s magazine and the anthology Year’s Best SF 14.
