I definitely did not get this far on my first read through, which is a shame! This one is where it starts to get really interesting. You have the siblings split up, mysterious cave scouts, the last Quagmire triplet, and the return of Carmelita Spats. Sunny's vocabulary gets even funnier, and her food gets even yummier. You learn way more about the Volunteer Fire Department, and get to see the hideaway. More about the sugar bowl, and the Snickets, and see the mysterious hidden letter from Lemony Snicket. This one also isn't so black and white. You get the first hint of the larger secrets of the Baudelaire parents. You get information on the schism of the VFD. You start to see a little of Count Olaf, and how he doesn't understand certain words--this was funnier in the earlier books, but now it ends up being kind of sad. You also get two of Olaf's supporters who straight up and leave Olaf, because they don't want do to evil things. Alternatively, you get the siblings confronting their own behavior and doing villainous things. Very interesting!
