Whispers in the Moonlight (VANCE HOPPER X Y/N)

This is a Vance Hopper fanfic that contains all letters except for the letter that comes after C. This novel is set in 1978, after the passing of all the boys, as well as Finney. You're at school when you abruptly get taken by the Grabber, being put into his van. You wake up in an empty basement. Just then, you see the ghosts of the boys including Vance Hopper. Will they help you get out or will you croak before then? Figure it out in this lipogram.

(OG IDEA but not my OG characters and plot)
