How does the author use imagery in the novel, Night Cry?

Naylor creates the mood of the novel and sustains it throughout by using vivid, precise imagery. Descriptions of thick vines that smother the trees and the fences and the telephone wires, of the steep bluff where Billy was killed, of the dark horse with the demon eyes, of the unearthly sound of the night cry, all contribute to the dreadful mood and tell the reader that something horrible is going to happen.
