There are undercurrents of H.P. Lovecraft in most of what Stephen King writes, but of all of his novels with such themes, which one is the MOST Lovecraftian?
I'd have to go with IT. Through most of the novel there's a foreboding sense that reality as we know it is falling apart at the seams, you have mere humans struggling to come to terms with this all enveloping cosmic horror, you have the concept of the "deadlights", and the protagonists maneuver through clashes between vast, unexplainable cosmic beings that are utterly indifferent to the fate of humanity. The fact that everyday objects turn into wellsprings of primal horror and disgust is another plus.
