Also in Tor.com, S.L. Huang wrote: "The Man Who Folded Himself" is in a category of science fiction I love, a category which I will refer to by the ungainly description of, “postulate a piece of science fictional technology, and then take every possible exploration of it to its logical conclusion and SEE WHAT HAPPENS.” ... the book folds in on itself like a fabulous origami of paradoxes that somehow make sense. ... It is one of the best time-travel stories I have ever seen. ... It is also very queer. The main character has sex with both male and female versions of himself, and becomes male and female versions of himself, and gives birth to male and female versions of himself/herself—I mentioned there’s really only one character in the whole thing, right?
