"The Order of the Third Circle, an underground medieval society operating in the present, has harnessed Fate. Their charge and reason for living is the book, an ancient tome, from whence letters are drawn, penned by a scribe centuries earlier. Gabriel Mondragon, a letter bearer made immortal by an elixir and a Lachesis ring, makes deliveries that in some way change the face of the earth. Trisagion knights guard the book and the bearer, but betrayal is on the wind. Civil war is imminent within the Order, and Mondragon must change the outcome.A pebble dropped into a lake forever changes the lake. The past lingers in the future and sometimes overtakes it."
