In three interconnected scenes, Hiroko Oyamada revisits the same set of characters at different junctures in their lives. In the back room of a pet store full of rare and exotic fish, old friends discuss dried shrimp and a strange new relationship. A couple who recently moved into a rustic home in the mountains discovers an unsettling solution to their weasel infestation. And a dinner party during a blizzard leads to a night in a room filled with aquariums and unpleasant dreams. Like Oyamada's previous novels, Weasels in the Attic sets its sights on the overlooked aspects of contemporary Japanese society, and does so with a surreal sensibility that is entirely her own.

Born in Hiroshima in 1983, Hiroko Oyamada won the Shincho Prize for New Writers for The Factory, which was drawn from her experiences working as a temp for an automaker's subsidiary. Her novel The Hole won Akutagawa Prize.
