[1] Spruill told Contemporary Authors, "As a novelist I'd like to do in another way what I attempt to do as a psychotherapist: to free a person for a few hours from the unhappier side of his life and turn him on to the constructive power of his mind".
[6] Publishers Weekly wrote, "An intriguing concept--a microchip inserted in the brain to cure blindness that also allows certain recipients to see the future--falls short of its potential in this poorly paced, digressive thriller".
[7] About Rulers of Darkness (1998), Publishers Weekly said, "By adding a noir-crime spin to his medical-horror formula, Spruill manages to grab hold of, and ride reasonably high on, the cape-tails of Anne Rice and the current vampire craze".
[9] Its sequel, Daughter of Darkness (1999), Kirkus Reviews wrote as having "less energy and richly layered excitement than before, but still notable in its field".
[10] Publishers Weekly noted some strengths of the Spruill in its review of Daughter of Darkness, including "his credible rendering of supernatural beings as members of a dysfunctional family with conflicting ideas about how to manage their problems shows a delightfully oddball sense of topicality, yet he is never less than sympathetic and balanced in his portrayal".
