David Vann’s riveting novel Halibut on the Moon reimagines his father’s final days, spent captive in the warped logic of depression. An aching portrait of a mind in peril, it confirms David’s status as one of the darkest and most talented fiction writers of our time, who counts Colm Tóibín and Lorrie Moore among his many admirers. David expounds his moving portrait of a family processing a loss that hasn’t yet occurred with The Age and Sydney Morning Herald’s Literary Editor Jason Steger.
