The Fuller’s Apprentice by Angela Holder

Josiah never looks for trouble, but somehow it always finds him. Bored with his work at a fulling mill, Josiah attempts a risky stunt. When a wizard saves his life and offers him a job as his assistant, Josiah jumps at the chance. Traveling around Tevenar, meeting interesting people, helping serve them with the Mother’s healing magic—what could be more fun?

But Josiah soon learns that while matters of life and death may be exciting, they’re seldom fun. Impulsive actions, even when taken with the best of intentions, can have devastating consequences. And some choices have the power to change Tevenar forever.
