I read this in high school and I still remember how freaked out I was while reading it. But I still couldn't put it down! I finally had to make myself put it down at night-which was the worst time to read any of the Fear Street books.
Currently reading EoS (finally), and I definitely do not recall ever seeing anything about this in any spoilers I‘ve seen (and I‘ve seen a lot). Definitely interested in seeing what‘s about to happen with this.
