When 24-year-old lawyer Romy learns that she is at her 'optimal stopping point' (the mathematically designated point at which one should select the next 'best person' who comes along in order to have the best chance at happily ever after), she knows it's time to get serious about her love life.
Ruthlessly rational, with a belief in data over destiny, Romy knows that reliability and consistency are dependable options, while passion and lust are transitory and only bring pain and disillusionment.
That's why sensible Hans the engineer is the right choice, as opposed to graphic designer James who exhibits the kind of behaviour that has got her into trouble before. Isn't he?
The twenty-first century may have brought technological advances in how we communicate, but this warm and funny novel shows us that the search for love is as fraught as ever.
