As Norah battles alone, yet again, through the bustling December crowds outside Fortnum & Mason, she hears the first notes of a busker's song that transports her back to the most romantic week of her life. Laughing under an Italian sky, knowing they had to part, Andrew made her a promise: If they are both single on Christmas Eve in ten years' time, they will meet under the clock on Grafton Street, Dublin.

But it wouldn't be Christmas without a few surprises . . .
