How does Terry Brooks use imagery in Angel Fire East?

Examples of Imagery:

"Remember what Mommy told you about angel fire? At the beginning of every day, the angels go all over the world and gather up a little bit of the love that mommies have for their babies. They take bits and pieces, just scraps really, because mommies need most of it for themselves, to keep their babies safe. But the angels gather as much as they can, and they bring it all together, before anyone's awake, and they use it to make the sunrise. Sometimes it's really bright and full of colors, like today, because there is more love to spare than usual. But there is always enough to make a sunrise, enough to begin a new day" (Chapter 15, pg. 188.)

"Shadows nestled comfortably in the corners and draped the bed in broad stripes. The puzzle and toys lay scattered on the floor. Harper's cup of apple juice sat half-empty on her nightstand. But the children were gone" (Chapter 24, pg. 311.)
