Yay, this thread!
I just finished Kameron Hurley's The Stars are Legion, which was incredibly gross and incredibly awesome. Enormous organic world-ships in space that are so old that everyone has basically forgotten how they work, rotting from cancerous disorders, and filled inside with lots of different, uniquely horrifying biosystems and cultures of people who don't even believe they're on a world-ship. There's a wonderful subversion of the whole 'live as one with nature' trope, because the people and the world-ships are perfectly aligned with each other: you can eat or drink anything you find, and you don't get infections in wounds, because the human/world-ship biology is so compatible; yet the flip side of that is a ton of body horror: women literally birth organic ship components, and everything can be 'recycled', which means lots of scenes in the deepest depths, where organic material (such as dead or not-yet-dead bodies) rots and is eaten by the recycling organisms.
In some ways Hurley's work reminds me of the opening scenes in Bones episodes: she takes such a delight in imagining the grossest possible things that could happen, and she has such a fertile imagination in rendering it.
I'm now reading Jeanette Ng's Under the Pendulum Sun, which is about Christian missionaries going off into Faerie to convert the fae, and not doing very well. Some of the elements are really beautifully imagined (especially the pendulum sun and the fish moon), but there's a weird sort-of-incestuous plot line that I'm not digging.
