Such caring is very unique for the wounded Gentry. His earlier undercover work has exacted a severe toll, and while he is psychologically competent, his life contains little enjoyment. A growing anhedonia is enveloping him. Dr. Nancy Joyce has matured, but she has never outgrown her childhood fascination with predators of the night.

Most readers will not have bad dreams, but the vivid descriptions of carnage are not pleasant.
