This is the second book of Marion Zimmer Bradley's Avalon Series.

Sets in Roman Britain, Eilan is a druid girl who is raised as a priestess. She rescues Gaius Macellius, a young man from a hole trap one day while out with another priestess, Dieda. They brought him home and healed him, not knowing that he is actually a Roman who bypasses their territory.

The druids and romans are enemies; and although Gaius has druid blood from her mother, his father however is a powerful officer in the Roman legions. It goes without saying that Gaius and Eilan aren't meant to be together, especially not when Eilan has taken her vows to become a priestess and her ability to serve the Goddess.

Though the theme of a forbidden love isn't new, the author has done a good job in creating engaging characters and I could feel their intense emotions through the narrative. This is a wonderful fantasy not to be missed in my opinion.
