First off, I just reviewed three books that fall into the memoir category, so if anyone is looking for ideas, here are Sketches From a Life, Emergency Sex and Other Desperate Measures, and Dress Your Family in Corduroy and Denim. They're all more essay collections than chapter-books, if you know what I mean, and I'd highly, highly recommend the Sketches From a Life by George Kennan.
Now for my list (cross-posted on my blog)! It's actually a pool, since I'm not sure how many I'll get to.

The Spy Wore Red by Aline Romanos (an international memoir of WWII intrigue by a duchess)
