A Retrieval Artist dies of a virus, yet his colleague, Miles Flint, believes the death is not an accident. Police detective Noelle DeRicci knows that the death of a young woman in the Moon's prestigious Extreme Marathon is not an accident. It soon becomes clear that both deaths are connected. Flint and DeRicci find themselves in their own race, one against time and a certain kind of madness that could threaten everything they know and love.

Booklist calls Extremes "an exemplary futuristic detective thriller." RT Book Reviews says, "This futuristic tale breaks new ground as a space police procedural and should appeal to science fiction and mystery fans." But Locus Magazine covers it all: "Extremes is simultaneously thriller, deftly plotted detective story, and SF complete with a form of Mad Scientist. Like the best of those genres, it also features well-drawn characters whose various viewpoints, areas of expertise, moral choices, and personal dilemmas all add to the rich mix."
