Lenardo, a master Reader with strong telepathic powers, meets Aradia, a Lady Adept who can use her powers both to heal and destroy. Together they defeat an evil Lord Adept. When the war's over, though, what then? Can they actually build an empire together? Each then decides to sacrifice their own powers to weaken the other's. Is this treachery--or something else entirely? And then a new menace appears on the horizon. There's a fine line between love and hate. The Savage Empire, Book Two.
