What is the author's style in Family Ties by Clarice Lispector?

Lispector employs a restricted omniscient point of view in "Family Ties," but the perspective shifts after the first twothirds of the story is told. It begins from the restricted perspective of Catherine, telling what she observes as well as what she thinks. Then after Catherine takes their son for a walk, the story is told from Tony's viewpoint, with his thoughts and observations narrated. The narration is "restricted" in the sense that only one viewpoint is treated at a time. If the narration described thoughts from both Catherine and Tony (as well as Severina) at the same time, the point of view would be unrestrictedly omniscient.
