It obviously owes a lot to Stephen King’s IT. But it stands on its own merits…and I give it extra credit because it was set in my home town. (https://en.wikipedia.org/wiki/Summer_of_Night)
I would also rate this above hyperion, like hyperion book 1 it crossed into the horror genre quite well, the rest of the hyperion books were a little bit too preachy but a good series never the less. RIP Dan.
