Andre Stackhouse Well I'm not sure of anything specific, but I'd say it qualifies as a modern fairy tale. Hansel and Gretel comes to mind. It's also sometimes compared to Coraline by Neil Gaimen, though that was a decade later. Coraline was influenced by Alice's Adventures in Wonderland, so I'd say it's fair to say there's a bit of that in there too. Anyway, this is all speculation about one of my favorite authors and books!
