'Well, we're different, we lead such different lives. I'm not sure how we'll go now without Annie. She was like Carrie, you know, in Sex and the City. Annie was our Carrie.'

Rachel knows what her friends think of her - but what they don't know is that she's currently in the thrall of a new relationship. And she doesn't want them to know, because when the truth comes out, fragile friendships will be put to the test all over again ...
