Varied Sentence Length

In “Harry Potter and the Goblet of Fire,” I found a good example of varied sentence length.

The photographs took a long time. Madame Maxime cast everyone else into shadow wherever she stood, and the photographer couldn’t stand far enough back to get her into the frame; eventually she had to sit while everyone else stood around her. Karkaroff kept twirling his goatee around his finger to give it an extra curl; Krum, whom Harry would have thought would have been used to this sort of thing, skulked, half-hidden, at the back of the group. The photographer seemed keenest to get Fleur at the front, but Rite Skeeter kept hurrying forward and dragging Harry into greater prominence. Then she insisted on separate shots of all the champions. At last, they were free to go.

I love how the sentences are long when it seems that the photographs are dragging on. At the end of the paragraph, when they are finally free to go, we get a short sentence that is straight to the point. “At last, they were free to go.” I am just now reading all of the Harry Potter books for this first time. Occasionally I think the sentences are a little bit too long and I lose interest.

I found an error in the same book. There is no need for the word “very” because the word “suddenly” means ­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­“very quickly.­­”
