When Stephen Donaldson finally wrapped up the Thomas Covenant saga, I started at the end and worked backwards. I could do the reading as long as I skipped a lot of pages. Can't really imagine putting up with Thomas Covenant before it was known how the series would end, but because the series took so long to complete, decades of readers were asked to do exactly that.

Authors with whom I was not happy were John Buchan and Talbot Mundy. Although Mundy's   "Om the Secret of Ahbor Valley" held my interest, I was disappointed by his other books.
