Book excerpt: My Father’s Glass Eye is Jeannie’s struggle to honour her father, her larger-than-life hero, but also the man who named her after his daughter from a previous marriage, a daughter who died. After his funeral, Jeannie spends the next decade in escalating mania, in and out of hospitals - increasingly obsessed with the other Jeanne. Obsession turns to investigation as she plumbs her childhood awareness of her dead half-sibling and hunts for clues into the mysterious circumstances of her death. It becomes a puzzle she she must solve to better understand herself and her father. Jeannie pulls us into her unravelling with such intimacy that her insanity becomes palpable, even logical. A brilliant exploration of the human psyche, My Father’s Glass Eye deepens our definitions of love, sanity, grief, and recovery.
