Edinburgh welcomes back one of Scotland’s most ferociously-talented writers. Andrew O’Hagan’s fifth novel, The Illuminations, weaves two linked stories together: the older woman, Anne Quirk, is a Scottish photographer struggling to keep hold of her memories, the younger man is her grandson Luke, an Afghanistan veteran whose experiences are ones he’d rather forget. Anne and Luke embark on a journey to confront a mystery from Anne’s past. Interviewed by Frances Hider at the Edinburgh International Book Festival.
