Settling down for a 24-hour flight to Australia, Lucy finds a text message on her phone - not from her boyfriend James, as she fondly hopes, but from a woman claiming to have slept with him four times in the past month. Trapped on the plane, she questions everything about her relationship with James. She finally calls him and he reassures her: it was only his mates playing a silly joke.James is a lawyer, persuasive and gorgeous and Lucy adores him. So why, at the wedding in Sydney of her best friend Molly, does she have niggling doubts, and find herself attracted to Molly's brother-in-law Nathan? The sooner she gets back to her regular life in London, the flat she shares with James, her job in PR, the better. Nathan is a happy-go-lucky surfer boy, with no prospects, no place to live, an almost-girlfriend in tow. And the other side of the world...Lucy - a girl caught between two distant continents - and two very different men...
