This month World Book Club talks to award-winning writer Siri Hustvedt about her novel What I Loved, a troubling, often turbulent tale of love, art, friendship and heartbreak set amidst the darkly flamboyant New York art scene of the late twentieth century. Scholars Leo and his wife Erica admire, then befriend, artist Bill and his first and second wives. Their respective sons Matthew and Mark grow up together until the first in a series of tragedies strikes; a calamity which devastates the whole community and changes everyone’s lives forever.
