Enchantress from the Stars by Sylvia Engdahl

A destructive alien race called the Imperials have settled on the planet of Andrecia to exploit it’s resources and displace it’s less advanced people. Engdahl seamlessly combines a technologically advanced alien race with a world set in a medieval era while creating a story that is timeless and appealing to all ages. Enchantress from the Stars is a unique mix of science fiction meets fantasy. Aside for the book cover, it would fit right in with today’s books. 'synopsis' may belong to another edition of this title.Although originally published in 1970, Enchantress from the Stars has a surprisingly modern feel to it. Ultimately, he must pit his innocent faith in the magic of his Enchantress from the Stars against foes who have come from a world beyond his comprehension. Despite both Elana's and Jarel's inner turmoil, Georyn's burden is by far the heaviest.

In his mind, Elana is the Enchantress from the Stars who has come to test him, to prove he is worthy of defeating the dragon and its powerful minions. How can he make a difference, when he alone regrets the destruction that is people bring? Georyn, the youngest son of a poor Andrecian woodcutter, knows only that there is a terrible dragon on the other side of the enchanted forest, and he is prepared to do whatever it takes to defeat it. The invaders don't consider the Andrecians to be human and Jarel has seen the atrocious treatment the natives get from his people. How can she possibly help the Andrecians who still believe in magic and superstition, against a force armed with advanced technology, without revealing her alien powers? Apprentice Medical Officer Jarel wishes that the planet the Imperial Exploration Corps have chosen to colonize didn't have a 'humanoid' population already living on it. Stowing away aboard her father's ship, Elana suddenly becomes the key to a dangerous plan to turn back the invasion of Andrecia by an aggressive, space faring Youngling civilization. If Youngling peoples found out that a supremely advanced and enlightened society like the Federation existed, it would irreparably damage their evolution. The Federation Anthropological Service would never officially have allowed Elana to be on this mission to the medieval planet Andrecia.
