Engdahl, Silvia Louise. Enchantress from the Stars.

How do legends come to be? This book tells the tale of two civilizations coming in contact. To Elena the world is science and techology. To Georyn these visitors are the stuff of legend and fairy tale. How will the Enchantress change the history of his world?
This book is more appropriate for an older reader who can follow a complex plot and comprehend the themes behind the story. For those readers it should be an enjoyable and thought provoking read.
