The Magician’s Apprentice(Prequel to the Black Magician Trilogy)
Kyralia is home to many magicians and their apprentices. Tessia dreams only of following in her father's footsteps, but women do not become Healers and all she can hope for is to become an assistant. When her father is visiting their town’s Magician, Tessia is cornered by a visiting Sachakan magician who assumes he can treat Kyralian servants like the women slaves of his homeland. In fighting him off, she manifests a natural magical ability. Tessia must become an apprentice magician or she will be exiled to protect the village from her uncontrolled powers. As she learns, Sachakan magicians intent on reclaiming the lands their empire once ruled make increasingly vicious attacks on Kyralian and Elyne villages, and Tessia finds both her skills as a magician and healer are in demand. And as the Magicians of Kyralia come together to defend their land, all wonder how they can possibly win a war against the powerful and ancient Sachakan Empire.
