You never forget the one that got away, do you?Nell Mason is extremely happy with her life – or at least, that’ s what she tells herself.

She’ s lucky to have a high-powered job as a lawyer, even if it does come with an eccentric set of billionaire divorce clients.

And she’ s absolutely fine living with her sweet, if slightly dull, boyfriend Gus in their London flat where they have very sensible sex once (OK, sometimes twice) a week.

She’ s definitely not stuck in a rut.But when Nell bumps into childhood friend and first love Arthur Drummond who broke her heart fifteen years ago, she’ s more than a little shaken.

The seemingly perfect life she’ s worked so hard for starts to feel, well, less perfect.

Maybe Nell’ s been kidding herself all these years.
