A woman is transformed into a mermaid but then cuts a seam down the middle of her tail to create legs, the area between her legs deemed therefore magical and mysterious. She becomes part of a carnival of sorts and spawns strange children with their own physical "traits" that differ from other children. One daughter is born with an elongated pointer finger with an eye at the tip through which thread could be run, as if her finger were a needle. This story was strange from the start and it only got stranger as it went.
I can't say I really enjoyed this story or that I understood it but I can say it is one I'll not soon forget. I have to give the author credit for that.
