How does Philip Pullman use imagery in The Broken Bridge?

Examples of Imagery:

"Everything was good suddenly, everything was fun, everything was as it should be in her mile-wide kingdom by the sea, as the last visitors trudged up through the soft sand toward their cars and the waves kept falling neatly and the sun sank toward the edge of the world in a welter of blood-red sky." (p. 15)

"Ginny sat with her book on the sofa in the endless cold silence that smelled of furniture polish, the silence that was sliced into regular little pieces by the tick of the tall clock behind the door." (p. 61)
