Le Clézio's book is lyrical, lush and intricately detailed. He portrays with great sympathy the epic journey undertaken by the Tuaregs. These are the 'blue men', a name that comes from their characteristic robes of indigo, a hue that rubs off on their skin. The individual characters, even the protagonists, are veiled to some extent we do not know the particular as well as we come to know the general. The landscape &mdash the desert &mdash is a pervasive presence. It is sensuously described the smells and sounds, the heat and haze rising from the land, the grit of the sand, the night skies, the creatures by light and dark... and the nomads themselves. This picture is not so much drawn as etched on the reader's mind, for Le Clézio repeats himself, applying his strokes with deliberate emphasis till the land comes to represent a state of mind, a state of being. Lalla, exiled from the free expanse of the open, thirsts for the desert. She hears its call the regular albeit mystical visitations of al-Ser, the desert warrior, represent a memory, a yearning for a lost way of life.
