My name is Natasha. I have a successful career, and a gorgeous penthouse flat. The trouble is, I'm in love with a man who already has a girlfriend. My name is Sophie. I have a man I love. He's gorgeous and we've been together four years. The trouble is, he won't propose. Natasha and Sophie met when they were eleven and rapidly became best friends. Natasha was always the more intelligent and Sophie the more beautiful, but it never came between them until now. Suddenly the tiny, niggling, inescapable fact of their envy for each other's life is trying to surface and a number of casualties are getting caught in the crossfire. Is a fading love worth clinging to at all costs? Is marriage the be-all-and-end-all? And can an affair ever be fulfilling? Natasha and Sophie need to learn that they might be hunting for happiness in all the wrong places.
