Deciding to sell the family timber business and give away his wealth to charity, Arthur’s family becomes convinced that he has lost his mind.

His university-bound daughter, Evangeline, wants to change the world but perhaps not at the cost of her own privileged life.

His son, Emil, good at maths and not much else, becomes more distant than ever.

And his wife, Yara, who arrives at airports four hours early and fears that AI and climate change will leave her children unemployed, just wants the doctor to run another brain scan on her husband.

Incisive, hilarious and unflinchingly human, The Greatest Possible Good asks fundamental questions about what it means to live a good life while introducing the world to one of the great families of contemporary literature.
