Dean Koontz is kind of like the RC Cola of horror/suspense novelists:
See RC Cola in the store
“Hmmmm, it’s been a while, but I THINK I liked RC the last time I got it”
Purchase and consume RC Cola
“I kind of wish this was a Coke, but it’s not that bad, might as well finish”
Several years pass, go back to step 1
As a side note, I LOVED Dean Koontz books back in the 80’s/90’s. They were fun and quick reads that are in the “high floor, low ceiling” realm of books.
