I’ve been turning this over since I pulled 'Eriette of the Charmed Apple' from a bargain bin last month. It’s a weird little book. The key character is obviously Eriette herself, the apothecary who lives alone in the thorn-hedge cottage. She’s not your typical wise woman—she’s brittle and deeply suspicious of everyone, which makes sense once you learn about her past.
The other major player is Captain Renard, the royal guardsman sent to investigate the strange sleeping sickness in the valley. He’s the straight-laced foil to Eriette’s chaos, but he’s hiding his own secrets, mostly about his dead sister. Their dynamic drives everything, this push-pull of mistrust and reluctant alliance. Oh, and the third key figure is the Appletree Man, this eerie, semi-mythical entity who only speaks in riddles and lives in the gnarled orchard. He’s less a person and more a force of nature, but his deals with Eriette’s grandmother set the whole plot in motion. Honestly, Renard’s lieutenant, Corbin, gets a lot of page time too, but he feels more like a device to move pieces around than a fully fleshed character.
I keep coming back to Eriette’s familiar, a mangy fox named Tally. The book leans hard on whether Tally is just an animal or something else, a piece of Eriette’s own magic given form. It’s never fully answered, which I found frustrating but also kind of fitting for the story’s mood.
