G.K. Chesterton is an excellent writer; he constructs his sentences and paragraphs very well and never jumps around between ideas, but always proceeds from one to the next methodically. Nevertheless, his writing can be a little dense and difficult to get through. At least, I had to do a lot of stopping and thinking and rereading when I read Orthodoxy and also for some of his other books I've read (The Everlasting Man, The Man Who Was Thursday, etc.)

So that's part of why I took so long to finish Orthodoxy: I wanted to be sure that I was completely understanding what Chesterton was saying, which meant that I generally didn't read the book right before bed, or while eating breakfast, or at any of my normal "book-reading" times.

Orthodoxy is Chesterton's "religious autobiography," that is, how he himself became a Christian (not an Eastern or Greek Orthodox, Christian, but a traditional - or "orthodox" with a small "o" - Catholic one). It's a fascinating look at a very sharp mind from another (but not too terribly different) age working logically from skepticism to belief. I found the book fascinating,particularly the section with Chesterton's refutation of the belief that all religions are pretty much the same. If you're interested in theology or just excellent writing, you should give G.K. Chesterton a try.
