Katri Kling is a social outcast of a woman who lives with her mentally challenged brother, Mats, and a nameless dog in a small room above a store. Anna Amelin is a wealthy book illustrator, doing flowery rabbits, and on the opposite end of the social spectrum. Katri cares only for her brother and wants things for him and he wants a boat. Katri is bright and realizes the way to get what she wants for Mats is through Anna. Soon both Katri and Mats move into the "rabbit house" along with the wolf-like dog. Katri is successful in creating a dependency in Anna and Anna's formerly trusting self is lost.
This is a thought provoking novel and one is never sure who is the true deceiver.
