I’ve read most of Stephen R Donaldson, and have a hard time with his style. However, he is imaginative.
I can fully appreciate that! It is a difficult style to read, and he's not become much better. I'm really not sure what impelled me to start, unless it was boredom, but about the time the Giants entered into the story it became interesting enough to keep me. OTOH, in the Great Weeding (of my library) I did not keep those books.
In the latest book he's introduced time travel.
