Reading A Clash of Kings, by George R. R. Martin. Even though I'd already talked to two other people, I felt compelled to stop him because he was reading while he was walking--must be a good book. Well, appearances are deceiving. It's not. It's long, boring and he's trudging through it because he has nothing else to read! He's simply in the habit of reading while walking.

A fantasy series he likes--Malazan Book of the Fallen, by Steven Erikson and Ian Esslemont. The series is, so far, six books long. Ten are projected. What makes it so good is the story--the series is long and dense, in comparison to the, in his words, "long and boring" Song of Ice and Fire series, of which Clash of Kings is the second book.

Something else that turns him off--heroes with moral failings. The hero should always act in a proper way.

Walking--with book
His strategy is to follow someone so that, if they detour to avoid, say, a post, he does too.
