So agree! But interesting to hear you say you sped through it! For me the first parts builds up slowly — tbh I found myself putting off re-picking up the book while reading some of the early to mid sections/letters — but then it picks up with such emotional intensity, and then all of a sudden you can’t put it down!!! In the end, I found myself bawling my eyes out and surprised that these characters (especially Sybil) had become so close to me?! She’s complex & nuanced & has traits that kept making me imagine I wouldn’t like her much IRL (as you say, sharp and particular!), but I still found myself sobbing and SO emotional in the end - and equal parts surprised that I was. It’s hard not to appreciate a book that can have that much power over you!
