Claire moves slowly on the ridge above the two valleys full of morning mist. The coast is to her left. On her right is the journey to Sacramento and the delta towns such as Rio Vista with its populations left over from the Gold Rush. She persuades the horse down through the whiteness alongside crowded trees. She has been smelling smoke for the last twenty minutes, and, on the outskirts of Glen Ellen, she sees the town bar on fire--the local arsonist has struck early, when certain it would be empty. She watches from a distance without dismounting. The horse, Territorial, seldom allows a remount; in this he can be fooled only once a day. The two of them, rider and animal, don't fully trust each other, although the horse is my sister Claire's closest ally. She will use every trick not in the book to stop his rearing and bucking. She carries plastic bags of water with her and leans forward and smashes them onto his neck so the animal believes it is his own blood and will calm for a minute. When Claire is on a horse she loses her limp and is in charge of the universe, a centaur. Someday she will meet and marry a centaur.
