Query: Frenzied tour de force

"Tour de force" I think is the term for an undertaking such as this. I frequently browse through Plotto though I haven't felt the need yet to copy one of its schemes for a plot of my own. This is surprising given that I find plotting difficult and cumbersome...it's almost an affectation with me and, as I know, with other writers of "literary" fiction, too. Unfortunately, "literary" means all too often that the story doesn't meet John Gardner's briiliantly conceived criterion of story as a " vivid and continuous dream" in the reader's mind...Plotto makes plot seem if not easy but at least doable, it takes away some of the mystery and replaces it by craft. Wholly recommendable!
