There are lots & lots of works in progress but some stories just seem to have been left for dead. One that springs to mind was The Orphan which just seemed to involve a young lad getting filled full of hormones so his guardian can, I assume, eventually have her wicked way with him.
It just dropped off (the story I mean), possibly due to unfavourable reviews...I always wondered where the author was going.
Any others that fall into that category?
