(1969) It's a story about culture clash and friendship on a world whose natives are sexually neuter for most of their lives, except once a month when they may become either male or female. I remember bouncing off this when I first encountered it in grade school, so was delighted to find it completely absorbing as a thought piece, as a story about cross-cultural friendship, and as an adventure yarn.
