u Murakami creates a rivalry of epic proportions between six aimless youths and six tough-as-nails women who battle for control of a Tokyo neighborhood. At the outset, the young men seem louche but harmless, their activities limited to drinking, snacking, peering at a naked neighbor through a window, and performing karaoke. The six "aunties" are fiercely independent career women. When one of the boys executes a lethal ambush of one of the women, chaos ensues. The women band together to find the killer and exact revenge. In turn, the boys buckle down, study physics, and plot to take out their nemeses in a single blast. Who knew that a deadly "gang war" could be such fun? Murakami builds the conflict into a hilarious, spot-on satire of modern culture and the tensions between the sexes and generations.
