"SFFWRTCHT: How do you approach creating aliens? Do you model them after human cultures? Mix and match or just improvise? 
JH: I guess I have some guiding principles, like “don’t make the aliens too human, but don’t make them so alien that readers can’t identify with them” . . . but in fact that’s not completely true. Sometimes you want the aliens totally inexplicable. I guess it’s one of those questions that really would require a book-length answer. If they’re modeled after human cultures, that’s probably for satirical effect. You read about biology and sociology and ecology and anthropology and whatever, and shake it all up and aliens come out the other end."
