Karen Traviss emailed me with the sad news that the truly exceptional historian, Richard Holmes, has passed away. His book, Redcoat: The British Soldier in the Age of Horse and Musket, served as a key resource for me while writing the Iron Elves. I feel fortunate to have known him through his writing.
