Why read this explainer

Compare the narrator's repeated philosophical interpretations with recurring behavior on screen. Tomas, Tereza, and Sabina's choices give freedom and attachment a narrower dramatic focus.

PlotGeeks note

Concentrating Tomas, Tereza, and Sabina gives freedom and attachment a narrower dramatic focus. Their relationships and the invasion carry ideas the novel repeatedly examines through narration.
