"Most medical thrillers deliver their chills in a cold laboratory atmosphere. Greer, a practicing surgical pathologist and research scientist, yanks the chain of the genre by setting most of his shocks in the scruffy outreaches of the Colorado High Plains. Readers are pulled into the back roads of illegal cockfighting before they realize they've embarked on an adventure yarn heavily laced with science fiction; the result is satisfyingly unnerving." -Library Review
