Jackieoh puts East of Eden into the 'Coming Of Age' genre, but I'm sure it would have been equally at home in 'Romance'.
The plot line is almost as old as erotic literature, but in this case it's beautifully handled, and that makes up for its longevity. Technically, the work is excellent, with few errors to detract from the story.
For some obscure reason (probably buried deep in my psyche somewhere, I've never had a sister), I'm particularly fond of sibling incest stories, and East of Eden is a classic of its kind. If you like that kind of story, you'll love this one. The main protagonists are sweet, gentle, and loving; all the drama derives from society's attitude to the act.
Just to digress for a while, I appreciate why there are laws forbidding incest, but they're mostly concerned with abuse, not love, coercion is a great evil, and for the perpetrators, any punishment short of death is suitable. Ignoring the law, the only real risk to a loving incestuous relationship, is a heightened risk of reinforcing recessive genes, and producing damaged children. How high that risk is I don't know, I'm not a geneticist. As far as the relationship itself is concerned, the Wiccans have the right of it, "An it harms none, do what ye will."
Getting off my soap box, and back to East of Eden, this is a great story!
Read, and enjoy!
