You would think there'd be scant space left under Salman Rushdie's literarywings for all the apostles gathered there, but they had best make room for Zadie Smith.White Teeth, her epic-sized debut novel, is more truly Rushdiesque than anything publishedin the last decade by anyone other than Rushdie. The 25-year-old Londoner is obsessed withthemes that are virtually patented territory: tragi-comic immigrant angst, crises ofidentity, history and faith, the state of nationlessness, the potpourri soul. Smith'striumph is that despite being stylistically imitative to the point of parody, she retainsher own voice - a funny, ironic one overlain with tenderness for her characters.
