questions on content..
the first is (ostensibly) a sci-fi horror set in a future time that the Universe is dying of old age. the horror isn't gratuitous or graphic and there's no violence at all, but it's a very creepy, disturbing story.
the second is a rambling tale set over several centuries (present day to about 400 years from now) and universes where the main protagonist changes from male to female during the course of the story and there's a lot of adult-themed content, but again it isn't gratuitous or graphic (but in all fairness I couldn't really take a theme of gender ambiguity and not mention the obvious consequences of such a transformation.) Think of Virgina Woolf's "Orlando" and that's about as racy as it gets i.e. not very.
the third is a story about 3 domestic cats trying to survive in a climate-changed world without humans, and it's quite violent (but in the same way that Watership Down is red in tooth and claw.) And yes, they're based on my cats.
