What is the author's style in The News from Paraguay by Lily Tuck?

Franco's point of view is even more startling than Ella's. The man literally has no sense of right and wrong. He is devoid of conscience or pity. Franco sees himself as the savior of Paraguay. As his situation worsens, he becomes more and more paranoid. Anyone questioning him, even in a constructive way, is seen as the enemy. He settles old or perceived scores ruthlessly and sadistically.
