This book is small but it packs a punch! Told in three sections and from three perspectives - the wife, her husband, and her best friend, the whole book takes place over the course of one day, and there are no repeats, each section picks up chronologically in the night from the other. It’s tense, sort of Who’s Afraid of Virginia Woolf vibes but with the added intensity of all of the characters knowing each other and all their weaknesses and sore spots very well.
