Book excerpt: Last Knight's Almanac celebrates life, love, and adventure, in the years following the death of King Arthur. But it also serves as a backdrop on which I can draw literary portraits of many of man's favorite things such as nature, astronomy, emotion, poetry, travel, history, fantasy, art, and so on. Arthurian legend is the main thread of the story and is also one of my favorite things, so this is important, too. What really happened inth Dark Ages? And yes, it's true, but only if you wish to believe it, that I unearthed these Chronicles from an iron box that was buried 1400 years ago under the Abbey of Glastonbury.
