I just read Mary Robinette Kowall's Lady Astronaut novels, set in the same world as her award-winning short story. It kept me turning the pages past my bedtime. It was meticulously researched for the most part, though I had a few questions, and at least one thread/question wasn't tied off to my satisfaction. No idea if she plans any more in that world.
As of a day or two ago, word is she wrapped the third book in the series, with plans for a fourth.
