To say that if something's compelling, it is, and that if isn't, it's not, makes no sense.
Some people create art, in whatever form, that can move or interest a wide audience-- or move
strongly those people it does move. What accounts for a best-selling song? Doesn't it connect with listeners in some fashion? There have to be ways to make writing compelling. The trick is to find those ways.
I've read chess games-- those of Bobby Fischer, say-- through the language of chess notation, and found those games extremely compelling. The reasons were A.) I was able to follow a kind of narrative line, where each move followed logically and inevitably from another; B.) the games offered surprise, or the prospect of surprise.
Or, the standard question regarding narrative: "What happens next?"
There have been some books regarded as "compelling," unable to be put down, by the majority of people who've read them. One is the Rider Haggard novel
She. The writer has no extraneous side plots, he maintains a very fast pace, and the story is rather fantastic. Once the reader plunges into his mysterious world, with a mysterious personality known to be at the end of it, it's hard to break off. The goal is distant, but always moving closer. You as the reader, like the adventurer on the search for "She"-- a most fascinating and beautiful woman-- want to get there.
Maybe a better example is the nonfiction history of the opening of World War I,
The Guns of August by Barbara Tuchman. This is a unique case, because the narrative line can be-- and is-- literally traced on a map. This is the plot: The German army invades France, with a set plan to encircle the French army and capture Paris. The story is laid out for the reader at the outset. The suspense comes from whether the German plan will succeed, or whether the French will be able to stop it-- and if so,
how they'll stop what appears to be an unbeatable plan.
As I'd been warned, I couldn't stop reading once I went past a certain point. The drama was intense, as the German army like a steamroller got closer, and closer, and closer to their goal, while at the same time one old French general behind the lines who believed he could stop the plan struggled to be allowed to do so. The main characters-- generals mostly-- are expertly drawn, but quickly drawn, because everything is secondary to the continuous narrative line, which could be drawn on a map, and of course was. It helped that there were good guys and bad guys.
I'm writing a novel currently and I'm trying to map out the plot movements and progress of the characters in a similar manner. I did a novella already like that for practice. (One'd have to read the ebook to see if it worked!)
(Or, think of actual movements, like a Beethoven symphony, where each movement is an unbroken line of musical language, usually gaining in intensity as the work nears a climax.)
