How does Suzanne Fisher Staples use imagery in Shabanu: Daughter of the Wind?

Imagery:

"A soft pain jolts beneath my ribs as I watch Mithoo nurse, and I think my heart is beginning to mend."

"Phulan looks regal with the red chadr over her shiny black hair. She looks like a flower blooming in the desert sunset, the wind whipping her clothes around her in sheets of color."

"Outside, the desert has been rearranged. Unfamiliar dunes roll where the land used to lie flat. Stands of shrub and thorn trees are no more. Nothing looks the same."
