Two brown girls from North London council estates want to be dancers. In the same dance class, the same shade of nut-brown, they are "two iron filings drawn to a magnet," friends before they speak. One, Tracey, is a natural dancer: intuitive, genius, even. The other, the narrator of Swing Time, is talented in another direction: She is an observer, a wallflower given structure by stronger, surer women around her. Unnamed, unsure, neither black nor white, the narrator is fittingly indistinct in this brilliant novel about the illusions of identity.
