They say that there is no such thing as a free lunch; well I guess there's no such thing as a free book either. On the other hand the bookclub I'm a member of would have liked me to think that this was one such, having been sent me out of the blue without any intervention on my behalf. I suspect they just had a massive overstock.
Onto the book itself, where unfortunately I have to say, and I hope this isn't itself a spoiler, that I don't think there's anything I can say that isn't a spoiler. Hmm, and they haven't even written any spoilers on the back. Anyway, as it happens it ties in nicely with one of my less-often exercised interests, and it's really quite nicely written such that you don't know what's going on. Not quite doubleplusgood, but….
18. Vinge, Vernor The Witling
Another one I picked up at at Picocon, this time in my general attempt to own everything Vinge wrote. This one's quite fun, but I hesitate to find any literary merit in it. It has a good take on esper powers though.
19. Stewart, Ian Math Hysteria
Aficionados will recognise this as the latest in Ian Stewart's series of books republishing articles from Scientific American. They tend to be quite fun and have interesting things in them (even if I've seen some of the Maths before).
This one looks at Monopoly and the Dots-and-Boxes game and Dissection puzzles and other funky Stuff. I don't think Stewart is quite another Gardner, but he does write good stuff.
