In the decade before the Islamic Revolution, Iran is a country at the brink of explosion. Twelve-year-old Yaas is born in Tehran, into an already divided family: Her father is the son of wealthy Iranian Jews who are integrated into the country's upper-class, mostly Muslim, elite; her mother was raised in the slums of South Tehran, one street away from the old Jewish ghetto. Yaas spends her childhood navigating the many layers of Iranian society. Her task, already difficult because of the disparity in her parents' worldview, becomes all the more critical when her father falls in love with a beautiful woman from a noble Muslim family. As her parents' marriage begins to crumble, and the country moves ever closer to revolution, Yaas is plagued by a mysterious, terrifying illness. But despite her ailment, when she learns that her father is about to abandon her and her mother-to immigrate to America with his mistress-Yaas is determined to save herself and her family. At once a cultural exploration of an as-yet unfamiliar society, and a psychological study of the effects of loss, Caspian Rain takes the reader inside the tragic and fascinating world of a brave young girl struggling against impossible odds.
