Houellebecq's controversial novel, which caused an uproar in France last year, finally reaches our shores. Whether it will make similar waves here remains to be seen, but its coolly didactic themes and schematic characterizations keep it from transcending faddish success. The story follows two half brothers, Michel Djerzinski and Bruno Cl ment. They have in common a minor Messalina of a mother, Janine Ceccaldi, who contributed most effectively to their upbringing by abandoning them--Bruno to his maternal grandmother, and Michel to Janine's second husband's mother. Bruno's is the harder life. Abused by fellow students at a boarding school, he grows into a perpetually horny adolescence, his sexual advances always rebuffed because he is ugly and devoid of personal charm. He spends the '70s and '80s exposing himself to young girls or masturbating.
