'One of the finest accounts of the mysterious workings of grief I have ever read.' Helen Macdonald 'Completely compelling.' Olivia Laing 'Read it with awe and sorrow.' Fatima Bhutto After the sudden death of his father, Nick Blackburn embarks on a singular, labyrinthine journey to understand his loss. How do you create an existence when all you can see is a void? The Reactor is a memoir about absence and creative possibilities, assembled like the pieces of a puzzle. Through philosophy, music, fashion, psychology, art and film, Blackburn travels a vast panorama of ideas and characters to offer an entirely new exploration of grief. This is a book about looking for and finding chain reactions and human connection - a work of enduring fragmentary beauty.
