"It's a creepy Scandinavian Narnia" - HA!

A wormhole opens up in a fictional equivalent of IKEA, and two of the most exploitable staff of one of these unpleasantly capitalistic superstores are sent through to retrieve a customer who wandered in by accident. That wormhole leads them to other versions of their own hell-store, and it's a hefty shove at businesses that treat employees like interchangeable and replaceable cogs. Finna is most successful for me when it sticks to these alternate stores - the passage in one dimension where employees have to pay for food in the store cafeteria with their own blood really is creepy. I'm less interested in the other worlds where the parallel is toned down or ignored, as it is on the ship, but overall it's still a fun, trenchant read, with a lot packed into a novella-sized package.
