I must need to read more, last short stories I read (maybe listened) were relatively tame about being on Mars I think, so possibly not the right collection. Maybe I didn't quite get their message either. Did listen to Something this way comes, which has its disturbing parts but not overly but nicely geared for a younger audience for sure. That said I started reading Stephen King and watching horror movies much younger than is probably expected, think first Nightmare on Elm Street was before 10 heh, King books were later of course.
