Waris Dirie's story puts "rags to riches" to shame. The "Desert Flower" started life as one of 12 children of a Somali nomad family, a people with no written culture, where the basic unit of currency is the camel. Faced at 12 with the prospect of marriage to a 60-year-old man she didn't know, she broke all the rules and ran away, surviving a traumatic trek across the desert to end up in London, as a maid to the Somalian Ambassador. It was in McDonalds that her striking beauty was "discovered", leading to a career in modelling and another as an ardent campaigner against female genital mutilation (circumcision). As a novel it would be unbelievable, as Waris survives circumcision, rape, arranged marriage, a lion attack--you name it, she's lived through it. But the book is remarkable less for its deliberately dramatic set pieces, and more for its haunting evocation of the little-told life of Somalian nomads, seen from a child's telling perspective, where life centres on the beloved camels, the horrors of womanhood are still an exciting mystery, and the nights are filled with the smell of frankincense.
