While pseudo-incest is not one of the sub-genres of erotica that typically does not top my reading list, I occasionally happen upon a story of this nature that peaks my interest enough to give it a go. Taboo Passions: Sylvia & Zach is one of those stories. I read this work initially in serialized form having received ARCs of the 3 parts from the author in exchange for my honest review. While I personally felt part of the story was lost in serialized form, it was none-the-less a really great, well written story which prompted me to purchase and add the complete novella to my collection for future enjoyment. I find many pseudo-incest stories between siblings to be simply salacious for the sake of making a few bucks and the motivations for character involvement to be weak and implausible at best. Here the 2 principals are bound by a mutual distaste for one another that transitions as the result of a incidental occurrence, in the form of Zach witness his sister masturbating, that fundamentally shifts Zach's view of his step-sister, allowing him to see past the spoiled little princess he has been teasing and taunting for years and awaken to the re-visualization of his sister as a sexual object. Though initial recognizing the taboo nature of their involvement, the 2 ultimate embrace what rapid culminates in a profound attraction for one another and ends on a happily-ever-after that is open ended enough that there honestly could be more to tell should the author wish to revisit this naughty duo. Definitely worth reading if you have even the slightest interest in the genre.
