The Librivox recording of The Worm Ouroboros is another favorite of mine, though of a rather different sort. This is a book to be listened to. It's an enjoyable enough read, but a trifle slow in places as Eddington indulges in detailed descriptions of clothing and furnishings, and I found myself skimming through extended passages. However, when listening instead of reading, those details are somehow transformed from near-tedium into something majestic. There's a different weight and sense of scope to them; Shakespeare's phrase "something rich and strange" seems fitting.
That's perhaps an apt pairing--Shakespeare, after all, was meant to be performed, not merely read silently to one's self--in the same way, whether Eddington intended this or not, The Worm Ouroboros is meant to be read aloud; it has that sort of cadence to it, the reader an observer of the scene rather than being immersed in the perspective of a particular character--rather like a fairytale on a grander scale. Like the story of Sam and Dean, it's about brothers doing extreme things for the love of each other, but in a rather different scope and tone. (Also, it's excellent for if you're trying to take a nap but can't get your brain to settle down so you can sleep. Jason Mills, the reader, has a very steady, calming voice, and the cadence of Eddison's prose is rather soothing.)
