Isaac at the New Year's party: Piranesi
Susanna Clarke's 2020 novel about a man living alone in an endless house of statues and tides, happy and a little lost. It won the Women's Prize for Fiction, sixteen years after her first novel, Jonathan Strange and Mr Norrell. A book about someone content in his own world while everyone outside it worries about him. Fair summary of Isaac at most parties.
