IF ONLY THEY'D SAID NO...

Clementine is haunted by regret. It was just a barbeque. They didn't even know their hosts that well, they were friends of friends. They could so easily have said no.

But she and her husband Sam said yes, and now they can never change what they did and didn't do that Sunday afternoon.

Six responsible adults. Three cute kids. One playful dog. It's an ordinary weekend in the suburbs. What could possibly go wrong?

Marriage, sex, parenthood and friendship: Liane Moriarty takes these elements of our lives and shows us how guilt can expose the fault lines in any relationship, and it is not until we appreciate the fragility of life that we can truly value what we have.
