There is a lot going on in this short novel and most of it works fairly well when deconstructed from the whole. There are elements of liminal spaces, nostalgia, fears of growing old, fears of separation, anxiety about losing yourself, and also (I'd say) a broad middle-aged push back against AI imagery. This last one takes some explanation, perhaps, and I will get to it.
However, while no single page is truly a problem and most of the pages are quite good there is a sense as a whole that these themes repeat and echo and get tangled up until they become kind of a chore. Which is surprising. A book that taps not only (1) the Gen X + Millennial nostalgia for the loss of the mall as a sort of cultural watershed, (2) the Millennial + Gen Z exploration of liminal space as a form of horror, (3) Boomer + Gen X handling of growing older and the change of the family dynamic, but also (4) how creepy mannequins can be FEELS like the sort of book that would have too much going on to have any time to proper loop back and linger. Except linger it does. Even when the latter portions of book introduces something else, something (5) *other*, those threads keep snapping taut into the same notes that started the book.
The notes sing and dance but the scent lingers. Muddies. The "being sent away from the world" portion would have likely hit harder if not tied by the neck to mannequins. I would love a novel about people having to survive in a giant "mall world" and all of its nightmare logic. The weird unexplored sections of the mall with *things* inside would possibly have been enough that a much longer novel could have grown from that instead of being backseated by that point by everything else. The elderly main characters seeing their own identity so long tied into the mall that is now dying could have been a full novel, horror or otherwise. The weird fiction elements towards the end could have swung so hard had they been more the point from earlier on, perhaps, instead of an added plot 80% into a novel that takes up 80 pages. Much like the mall-in-miniature menagerie imagery towards the end of this book: things are too compressed and the visuals are too cluttered to make sense.
As for my AI jab, there is a bit towards the end (but also before that) where the mall inside the mall is described as things being fused together and store brands become nonspecific nonsense that feels exactly like an image you might see if you went to Dall-E and typed "A typical American mall scene" and just let it roll. I actually tried it out myself and got an image with store names like "SamoGocok" and "Sbarlo" and people are sort of compressed together and the store merchandise is nonsense on the verge of making sense: a scene I have never seen but also have, a badly remembered memory.
Back to the book at hand, I Found a Lost Hallway in a Dying Mall [a title so close to a Chuck Tingle title that I feel almost compelled to add "...and Fell In Love with a Gay Perfume Kiosk"], my overall review is that is maybe two great short stories with a couple of interestingly odd vignettes occupying a space where none can quite function fully as they were. Which is perhaps a metaphor. A fairly early 2000s style of bizarro writing meeting a fairly 1990s style of suburban horror crammed too tightly together like that last heyday of the mall ecosystem itself.
Cutting any two elements and expanding more on the remaining would no doubt have made it flow much more strongly. Maybe just lose the mannequins. It is like clowns in the recent decade of horror or the Necronomicon. Too pat. Too self-contained. Too much weight on their own to not substitute elements that are actually more novel (pun!). I appreciate that horror novels about nostalgia and liminal spaces can very quickly get too maudlin and too technical (or too empty) without having some monster to haunt your labyrinth but all the same very nearly everything I loved about this novel was hidden away in between the moments where the obvious scary thing was trying to snag my attention.
All said, I like what Farthing is getting at here and will definitely read more. 3.5 stars, rounded down.
