In the year 2248, Mars is ruled by a Politburo-like committee that actively discourages dissent as well as travel and exploration of other planets. Scientist Emma Weil becomes involved in a covert plot to convert a stolen ship into a self-supporting spaceship. She turns down a chance to accompany the starfarers, and returns to her beloved Mars where she joins the revolution already in progress.
Three centuries later, archaeologist Hjalmar Nederland unearths a governmental cover-up of the true facts behind the old revolution. At the same time, a Stonehenge-like monument is discovered on the north pole of Pluto, and Nederland sets out to prove his theory that the monument is connected to revolutionaries and their contemporaries who left for the stars. Seventy years later, his great-grandson Edmond Doya becomes convinced that Icehenge is a hoax, and attempts to disprove Nederland's theory.
In addition to futuristic issues such as interstellar travel and the terraforming of Mars, Robinson's characters grapple with politics, careers, families, and aging. Icehenge is a worthy introduction to the author's winning combination of hard science and believable characterization. --Bonnie Bouman
