When a stranger tells her she's a mage, Ailith is intrigued but she's also afraid. Magic is heresy, and heresy means death under the Temple Law. Even literacy is suspect in a girl of her background, and her sister's impending wedding only serves as a reminder that she should be focusing on her future. Then a local priest asks her to rescue his son, and she starts to wonder if her talents could be a blessing, after all.
The Lord Baron of Watersmeet, Leofwin isn't accustomed to welcoming uninvited visitors. A commoner turning up at his gates should be no more than a minor footnote to his day, but something about Ailith catches his attention. Alchemy can be lonely work and an apprentice might be just what he needs.
As their lessons grow into shared experiments, Leofwin wonders if he might even trust her with his greatest challenge. But Ailith can't forget why she came to the castle.
