Quick Plot Overview
The novel follows Tova Sullivan, a widow who works nights at a small-town aquarium, and Marcellus, a highly intelligent giant Pacific octopus. Through alternating perspectives, the story explores how quiet routines, unexpected friendships, and hidden connections shape the lives of people dealing with loss. As Marcellus observes human behavior from his tank, he uncovers truths that gradually link Tova’s past with the present, leading to emotional closure rather than dramatic confrontation.
