If you enjoyed Semiosis, you'll want to read Interference. It picks up the story and further fleshes out the world of Pax, while updating us on the colony there as well as giving us a few glimpses into what became of Earth in the meantime. Super quick read thanks to the sparse style but it never lacks creativity and I enjoyed every bit of it. I'm crossing my fingers Burke continues the story because there are still plenty of questions I'd like to see answered.
