That’s hard to say, because I’m not sure there’s much trivia I know. The only thing I can think of, and hence favorite by default, are the bees on Tam’s breastplate.
Old time reader/listener. Meaning I read the first half dozen or so when they came out, possibly all through CoT. But we downsized, got rid of the books, and got the complete audiobook set instead. So I’ve done one read through and one audiobook listen (which duplicates only those books I had read), and haven’t really returned to them since listening to the last 3. Meaning I don’t remember the details and constantly look things up, though I did buy the e-book of the Eye of the World recently.
