She was meant to stay indoors but everything looked varnished and bright after the rain, so she put her coat on and went outside, then came back in and slung the camera over her shoulder. Through the sopping grass and down towards the river. It was wide and brown today, and it rippled and churned. There were deep creases when it went round rocks and a hollow, clunking noise. It looked strong, like a muscle. When she threw in a stick, the stick didn't float on the surface – it got dragged under, as if something had reached up to grab it. She walked along the bank and there was the bridge she'd seen in some of the photos – it had rusty railings and a broken plank in the middle.
It's an excerpt from a novel 'Weathering'. And I've never really read any English novels so these kind of sentences are hard for me to understand..
Does this 'Through the sopping grass and down towards the river.' sentence just describe the background image? There aren't any verb or subject so I'm confused.
Also there are so many 'it's and I don't understand at all what it means.
