The Fury and the Power
by John Farris
Eden Waring has known fear in her life. She is an Avatar, a talented young psychic with the ability to produce at will her doppelganger - her mirror image, who calls herself "Gwen" and possesses remarkable powers beyond even Eden's gifts. Gwen can be invisible to mortal eyes, if she chooses to be, and can even travel back and forth in time.
