The Lost Daughter by Elena Ferrante
Leda, a middle-aged divorcee, is alone for the first time in years when her daughters leave home to live with their father. Her initial, unexpected sense of liberty turns quickly to ferocious introspection following a seemingly trivial occurrence. Ferrante's language is as fierce and finely tuned as ever - she treats her theme with an intense, candid tenacity. A complex, controlled and piercing meditation on motherhood and womanhood.
