It's insane how many callbacks Ferrante references from the most obscure lines of the first book, the second. Unspoken as well. She unearths a plethora of parallels with a subtlety that you'll have to dissect through otherwise you'll miss them, and they'll stay buried in your subconscious. It makes me feel like I'll keep missing masterful details until I reread, and then reread again. It's a good thing I'm consuming these books like they're comics (her writing holds you at gunpoint).
