For people interested in things like: Ice Climbing, Chinese Parenting, Ultrarunning, Icelandic Volcanoes. and Game Theory*, for people interested in pretty much anything, I’ve got a recommendation for you: Tunes for Bears. I might be slightly biased (it’s my brother’s blog), but it’ll make you smarter just to read it.
*Common denominator = extremity.
And one more link, for kicks: my first book review. It’s about a great collection of stories called Widow, by Michelle Latiolais. The review is up on the San Francisco Chronicle website.
