Well this was an adorable little slice of a book. A wormhole opens in a giant IKEA-like store, a customer wanders through it, and two disgruntled employees (who have recently broken up and have been trying to avoid each other) are assigned to go fetch her, using a FINNA device to track her down.
Ava and Jules hate their soul-sucking retail jobs but love each other, even though their various neuroses have made them incompatible. When the employees are all herded into a break room to watch a Dharma-like video about the dangers of rogue wormholes (apparently when buildings are large, confusing, and similar enough to their counterparts in other universes, the borders get blurry), Jules the stifled adventurer volunteers to go through and look for the lost customer. Ava, still smarting from the recent breakup, absolutely does not want to go with them, but is assigned to the task as the second-most junior employee. The pair find themselves in weird lands, where chairs and kitchen utensils grow on trees, or the store cafeteria demands blood as payment.
It’s a light, YA-like romp that manages to tackle gender identity and mental illness in interesting ways, even while keeping the story zooming along.
Also, the author graduated from my alma mater, the University of Kansas, so I am a bit biased.
