Moving targets

the long version

"Mercedes Lackey's Valdemar is an ancient land where the peace is kept by a very special corps of protectors: the Heralds. Chosen from all across the kingdom, from all walks of life, and at all ages, these unusual individuals are Gifted with abilities beyond those of normal men and women. They are Mindspeakers, FarSeers, Empaths, ForeSeers, Firestarters, FarSpeakers, and others who are uniquely suited to protect their realm. South and Chosen by mysterious horselike Companions, they are trained to be emissaries, spies, judges, diplomats, scouts, counselors, and even warriors. Bonded for life to the Companion who chooses them, the Heralds of Valdemar ride patrol throughout the kingdom preserving the peace and, when necessary, defending their land and monarch."--p.
