This post catches me up to speed. I am near finishing this thriller by Williams. He is something of an obscurantist - intentionally difficult prose through which one must wade to catch a cosmic glimpse of meaning - but the denseness adds to the allure for me. I first read this in a wonderful class on C. S. Lewis and friends by the baffling, delightfully eccentric Dr. John Pilkey back in, what, 1996? Wendy read this recently, so I look forward to discussing it with her soon.
