Swift and the Black Dog

Once there was a revolution and Jack Swift killed a tyrant. It was an ugly war and he and his friends paid a high price for victory. A decade later, all Jack wants to do is stay out of sight and never use his power to call down lightning. But not everything's over -- the new government is troubled and Jack finds himself drawn into involvement by a young man who's not only absurdly idealistic, but also thinks Jack is some kind of hero.
