Hmmm... No, the only correlation between Donaldson and Wolfe that
I share is that they're both hard to get into. However, whereas I
forced myself to finish the 1st Donaldson book, and had absolutely
no interest in reading any more in the sequence, I found I couldn't put Shadow of the Torturer down once I got about 1/4 of the way into it. It does take a bit of getting used to, because Wolfe writes in a deliberately obscure manner that forces you to use more imagination than most other SF books. I found that Severian and the whole culture portrayed in the book fascinating; I finished SoT in one sitting and ran out the next day to buy the other three books, which I finished post haste. I only wish there were more!
