This is one of those rare examples of King's books that never should have seen the light of day in this form (like The Tommyknockers
). It suffers from bloating, uninspired telling of uninteresting facts of not particularly involving characters in the first place. The closest King gets to unsettling (and he aims for Lovecraftian universe) is a small episode of curing the heroin addiction with secret electricity.
Even grand finale falls rather flat and unexciting ( just bringing someone back to life, really? It was the beginning of Frankenstein, after all.
I still believe it would make a good short story, if only heavily edited to keep just those few important events (probably rearranged in reverse order).
