Die Ahnen von Avalon

Blurb

Ancestors of Avalon is a 2004 historical fantasy novel written by Diana L. Paxson, and based on an idea of the late Marion Zimmer Bradley.
The book is one of 7 prequels to Bradley's popular fantasy novel Mists of Avalon. The characters of Ancestors of Avalon have appeared earlier in Bradley's fantasy novel The Fall of Atlantis. Ancestors is the missing link to the implied connection to the mythical Atlantis in Bradley's Avalon-series.
