Maps in a Mirror (center): 675 pages. Read cover to cover in eight days. I think there may be something
wrong with strange about me. Contains a whole mess of Orson Scott Card fiction, and bits of him commenting on it. Quality is all over the map, because this spans his entire career at least up until publication. (But does not cover his entire career. It's only a collection.) I could probably comment on individual stories, if asked.
Epic (left): 364 pages. Read in a day or two, but certainly under 48 hours. Took a break from Maps in a Mirror to read this. Set on a distant planet where economic life and a large fraction of the economy are based around a video game. YA, but there are strong undercurrents of moral and economic philosophy.
The art of Thinking Clearly (right, open): around halfway through, I've read something like 150-160 pages. A collection of short essays (generally 3-5 pages) on thinking errors. Each prevents the error in a colloquial way, some evidence and/or arguments for it, and usually some clues for how to avoid it. I'm not sure how useful it is. It's generally not perscriptivist, but I don't know whether that's a good thing. Though it probably is.
Not mentioned: the large amount of internet reading and downloaded computer-only reading I did this week. Nor the chunks of magazines I read.
Also not mentioned: The first three episodes of season one of Star Trek: Voyager I watched, the first three episodes of BBC's latest Sherlock I watched, or the episode or two of Star Trek: TNG I watched. I'm pretty sure I watched a bit of TNG, anyways. I liked Voyager better, so that's what I stuck with.
