When a marriage ends and a first love reappears, Celine Lewis is about to find out that moving on is as complicated as going back. Three years after seeing her first love, Patrick, quite by chance in London, Celine's ten-year marriage to Mike is over. She is running her own business, a professional matchmaking service called The Love Market, in Northern England, and coping with the unanticipated heartbreak of a marriage ending - not to mention her quirky twelve-year-old daughter who blames her for the split. Then, out of the blue, Patrick emails. Celine is tempted to find out if all the old feelings can still possibly be there, but then Mike has an unusual proposition for her. One that forces her to question whether a divorce really means it's over.
