This new collection of short stories by Greg Egan delivers more of the hard, thoughtful, Australian Cyberpunk and Science Fiction that he is famous for.'Luminous' is more than just your average Cyberpunk techno-romp, Egan deals with the big issues. For instance, in 'Mitochondrial Eve', Egan invents the field of "quantum genopaleontology" in order to examine issues of religion, tribalism and racism. Another story, 'Mr Volilition', draws on Minsky's pandimonium model of the mind, and describes the effect on a murderous theif when a neural monitor dispels the myth of free will. The title story, 'Luminous', deals with the very nature of reality, as two mathematicians struggle to prevent a pockets of "alien mathmatics" slipping into the hands of a corporation with sinister motives. Great stuff ! Highly recomended. I look forward to his next novel.
