edmond hamilton

Hi folks, I get a general impression that Edmond Hamilton's (husband of Leigh Brackett) SF isn't that really that highly regarded (Moorcock's views aside) but what about his horror? I never knew he had written any but trawling through the site of a newly disacovered niche publisher I came...

It's a fantastic classic sci-fi book and seems almost forgotten. A while ago one could only get the novel from used bookstores. Now it's back in print and also available at Amazon. There's also a sequel but it doesn't come close in my opinion... Any fans of this author around?
