Well, I had a major EUREKA (or, maybe, it was more like a DUH!) moment today; while working on my characters' GMC, to make sure all my ducks were in a row and packing howitzers, I realized my VILLAIN's needed work. I had absolutely no concrete reason for his behavior. How had that happened? And, since he shows up in three books (each book has its own primary villain. This guy becomes the primary in the third book,)it would be nice if he had, if not a method, a MOTIVATION for his obscenely obsessive behavior.
It's the synopisis' fault. All of it.
