Rachlin illuminates the private and public consequences of the Islamic revolution in her latest novel of 20th-century Iranian life (Heart's Desire
). Nora Ellahi, the daughter of an Iranian doctor and his American wife, lives a sheltered life among the economic elite of the oil city Masjid-e-Suleiman in the 1970s. While dissatisfaction with the ruling Shah and resentment of foreign influence spills over into street demonstrations, Nora grows increasingly attracted to her adopted brother, Jahan, a full Iranian, and their sexual affair blossoms during a summer at their country house in Meigoon. Nora and Jahan's illicit relationship plays out against the backdrop of a restrictive society, and the burgeoning revolution lends tension to each daily activity. The novel's less propulsive second half is set in America. When the revolution reaches Masjid-e-Suleiman, the Ellahi family leaves Iran and resettles in Long Island, where Nora revels in the more liberal society but the rest of the family struggles to adapt. Ultimately, Jahan must choose between the freedom of America and the patriotic call of serving his birth country in the Iran-Iraq war. Though Rachlin sometimes sacrifices art for clarity with her straightforward writing, she delivers a complex portrait of a divided Iran. (Mar.)
