Reading The Forest House does seem surprisingly to push me toward reading this one. I cannot compare it to The Mists of Avalon, which I haven't read yet, but as a standalone is quite good. I enjoyed experiencing all the connections that this volume in the series contents, and it sent me back again and again to check details about the Forest House. In any event the stories are engaging on their own and this book could be enjoyed independantly of the others.
The story itself is fairly straightforward, in three parts. The life of Gawen, son of the formerly High Pristess of the Forest House Eilan and the Roman soldier Gaius. (The Pristesses of the Forest House were forbiden to marry or bear children. After Gawen was born, Eilan could not bear to be parted from her child. She defied her granfather the Arch-Druid to keep her son with her, and he agreed on condition that it was not known Gawen was her own child. But the Druids found out ')
The Roman Carausius and High Priestess Dierna who must use all her strenght, wisdom and love to guide Avalon through treacherous world of time ... And the more familiar Viviane's life as a young adult, from her childhood through the day she became High Priestess, Lady of the Lake and keeper of the Grail ...
The story starts strong and is nicely done. Though it seems to me that I read the series backwards, both books were equally wonderfull but I definitely enjoyed The Forest House much more than this. Meanwhile I am of the opinion that you should read this book before reading the Mists of Avalon.
Bradley's narrative is impressive and her plot is believable, as are her characters. They are fairly sympathetic, fleshed out and human. On the whole, though, the story is dramatic but pretty cool. The ancient rites of learning, healing and magic and some powerful women against the onslaught of the Roman army.
It is a worthwhile and compelling read and grips the reader tightly in the style of Marion Zimmer Bradley.
