Favorite non-fiction:
Spirit Catches You and You Fall Down - Anne Fadiman (this book has a string TE fan club, as I recall) - also by her - Ex Libris - a must for book lovers!
I'm a big Karen Armstrong fan (Lise, were we twins seperated at birth?) - I just read her Biography of Muhammed, which made me want to re-read Satanic Verses (an "all-time top 10" book for me)
I liked Jared Diamond's Guns, Germs and Steel, and have almost finished Collapse (sort of depressing...)
I haven't unpacked my non-fiction, so not much more is coming immediately to mind - oh, except essays by Joan Didiion and Barbara Kingsolver (esp. High Tide in Tucson)- I love a good essay.
Ok - off to bed to read -
Keep calm and carry on...
