Polly has been married to Arthur for ten years when she meets James Hammond. He's her Road Not Taken. The One That Got Away. He's also rich, and, in one week he's inviting his converted monastery in the country to give her the job she's always wanted. He also wants her.

Her best friend Em says, 'Go.' Em's spent two years with a man who resists commitment like a dog resists a bath. She understands how it feels to be stuck. But she has her own interest in Polly's husband. Meanwhile, Arthur says: 'Stay. I can change.'

But can he? After ten years, can you learn to love? And if you can, would you still choose your partner?
