Romily Parker is a woman on a mission. On the last Saturday before Christmas, (shortly after disastrously declaring her undying love for her best friend, Charlie) Romily has a sudden, brief encounter with a gorgeous stranger who might, just possibly, be the man of her dreams. It only takes two small words - 'Hello, beautiful' - and one, heart-stopping kiss to make up her mind - she has to find him again.

Giving herself a deadline of the following Christmas Eve, Romily commits to spending a year searching for the stranger - a decision that divides her family and friends.
