Dark Lady 1 and 2 were just sublime. The shower scene was just so perfect; damn, but I liked Sergei! And that stroke of his cheek - just a perfect touch. Lethal lover, if ever there was.
Dark Brother was good too, I like Franco. I don't think that any reading experience remains taboo when Voinov writes it - he leads the way and I just follow. The mark of a great story teller.
