Sibling Rivalry - Attero Not for the faint of heart, and a VERY taboo storyline. Sibling incest. Short story/novella with a very abrupt and, though expected, WTF ending.Only a few small typos, and fairly well written, but more about titillation than a good storyline. I'm tempted to only star it with 2, simply for the 'porn-like' telling, but that's because of my personal discomfort. If it had not been true incest, I probably would be thinking a solid 3, so we'll go with that.
