Ms. Wolitzer is a very fine writer (e.g. The Wife) but this is her best book so far. This is a sensational relationship book: relationships between men and women, but most importantly, between women. The themes of feminism and an apparently supportive sisterhood are linked to some astonishing acts of betrayal. The characters are vivid and realistic and the progression of the story is superb. Highly recommended; one of the best in 2018 so far.
