Simms has his reasons, although it's spoiler territory to discuss it. I think it's not long now, though, IIRC.PERSONAL STATEMENT
Another terrible example of being digested by one of the Fears. We also see more of Michael Crew, who went from being chased by lightening monsters to BEING a lightening monster, so again--it appears that some get used by these forces. It’s funny that Simms thinks it’s the book, when to me it’s obviously not--the books aren’t the source of the power, Simms, they’re just the keys to the door.
