This comprises issues 18-23 of Y the last man. The first three stories, under the title of 'safeword', are dark and psychological. Yurick goes through another key stage of self realization and a few other plot elements like the mysterious amulet and three hooded strangers chasing after it are alluded to. The next two stories are about a militant group of women under the ironic name of the Something Brotherhood who have pledged allegiance to the state of Arizona and consequently blocked 90% of the supply chain connecting the east and west coasts of the US. They think the government somehow had something to do with the plague that killed the men. Here Vaughan's explorations concern politics and economics. The system of money has all but broken down and barter is the main mode of exchange, food the most valuable currency. After Vol 3 i almost thought the series was going downhill but this has reinstated my initial interest. Sure, the plot is a little linear but Vaughan does manage to introduce some elements that surprise you as they connect back to some unexplained incident in the earlier books. So there is some depth here, though not in a too complex way.
