It depends on how much you liked the story up to this point.
Although the beginning is good, it also has some POVs that I didn't enjoy as much. Most of the excitement loses its impact because I already know what's going to happen, and instead, I start noticing the flaws. That's why I avoid rereading a novel twice; it ruins the nostalgia of the first read for me.
So, if I were you, I would just read the chapter titles and reread the ones that seem more interesting until you reach chapter 371, then continue reading the rest of the story normally.
