So for about the last two years, I've been reading just about everything of his I can get my hands on. I've finished probably about two-dozen of his stories, including some of the larger ones like "The Shadow Out of Time" and "The Dream Quest of Unknown Kadath".
I've read a bunch of his Cthulhu stories, in addition to a dozen or so of his "Dream Cycle" material. I can definitely say, I don't share Lovecraft's infatuation with dreams and whatnot (good stories they may be), but his Cthulhu works are some of the best fiction I've ever read. He's quickly become my absolute favorite author.
