Leigh M. Lane sets World-Mart in a future America where a single corporation has effectively taken over both the economy and the government. The protagonist works inside the system, doing what work means in a world where there isn’t really any other employer left.
Lane’s worldbuilding extends naturally from existing corporate retail trends. The book asks what the logical end state of that direction looks like, with the personal toll on the people inside the machine taking center stage.
The science fiction here is more political than technological. The story is interested in human consequences, not gadgetry.
For readers who liked Margaret Atwood’s MaddAddam trilogy or Naomi Alderman’s The Future, this is in adjacent territory. Less literary than either, more focused on a specific economic premise. Worth reading for SF fans interested in near-future political fiction.
