The last few books I've read have been exceptionally well-written and/or interesting:
The Amazing Adventures of Kavalier and Clay: Won the Pulitzer for fiction, understandably. I just can't say enough about this book. It draws you into the lives of the protagonists and takes you from Prague to Brooklyn to Antarctica to Manhattan and along the way makes you care about them deeply. With one or two exceptions, it never crossed my mind to doubt that such truly amazing adventures could be happening to real people. (This was a selection from my mothers' club book group.)
The Jesus Machine: How James Dobson, Focus on the Family, and Evangelical America Are Winning the Culture War: Dobson has been one of the most powerful non-elected men in politics over the last two decades. This is an unbiased (really) examination of how and why he got there, and also how the Christian Right became so powerful that it was able to pull off feats like winning Dubya the 2004 election.
Three Cups of Tea: I'm only about a third of the way through this book, but I'm totally hooked. The writing is wonderful and the story is truly incredible. It follows an incredibly fascinating person that I can't relate to at all to a place I can't imagine but makes me want to be along for the ride. (Our latest book club selection.)
