I was profoundly effected by Canticle when I read it as a teenager and wondered what others thought of Horse Woman.

I think I found its fame and success somewhat offputting. I remember avoiding reading some works because it seemed they were everywhere, all over the racks and in my face. I avoided buying and reading any Tolkien until my high school held a book fair, "The Hobbit" was the only book offered that was remotely SF or fantasy, and I felt I just had to buy something. I didn't read it until the following summer (and then I simply had to seek out and move on to "The Lord of the Rings")

I think, one by one, I caught up with everything I avoided in this way. I caught up with "Leibowitz" a few years after that. (Come to think of it, I bought it used.)

(I do like a lot of Miller's shorter works very much, though. He was good. Don't pass up "Dumb Waiter," "The Darfstellar," or "Vengeance for Nikolai," if you can find copies.)
