YES. "Killer Angels" is a brilliantly evocative portrait of a time and place, even though some historians will tell you that it plays a bit loose with the actual history.
While visiting Gettysburg a couple of years ago, I saw a book for sale that — while praising Shaara's writing in its foreword — went into a blow-for-blow refutation of some of the passages in "The Killer Angels."
Anyway, savor that book, HLGStrider.
Me? I'm wading into Dan Simmons' sci-fi epic "Hyperion," which is sort of like "The Canterbury
Tales" set in a distant, surprisingly fleshed-out future. Simmons doesn't hold hands or stop the narrative to explain all of his invented language and speculative history. Rather, he trusts the readers to figure it out as they go. As bewildering as it all seems at first, it makes the act of discovery a joy as the pages turn.
Apparently it's got a fat sequel too, so I've got my reading schedule set for awhile.
