Essef - A near-future society that is ravaged by AIDS. When scientists engineer a cure, part of the cure, however, renders women sterile to a second pregnancy by a man of the same blood type as the first (eliminating the chances of another child with the same man). Scientists create an altered human, the Mark II. Unknown to them until the children reach puberty, they are cyclical hermaphrodites, going from male to female and back again every other month. Society's response is typical and intolerant. A fast-paced, solid science fiction novel with a terrific message that isn't preachy!
