Susan Cooper's The Dark is Rising series, not so unusual, but I was a child hipster and loved The Grey King the most and read it over and over and over again, to the exclusion of all the rest. I was completely fascinated by the landscapes and the mists and the nature-magic and the Concept of Wales™. I imprinted hard on the myth-drenched faerie-ness alongside the almost James Herriot-like relationships to animals and agriculture (and, looking back, probably the intense subtextual queerness). Being an Old One in the special way I made up inside my little eight-year-old head probably gave me some interesting neural pathways.
