Found as an infant in a desolate, plague-ravaged village, Ada was raised by a healer who taught her the ancient arts. Now, determined to become the clan's new healer, she faces her greatest challenge yet.

Lachlan MacNair, the laird's stern and unyielding son, doubts her abilities, seeing only her youth and defiant nature. When a servant mysteriously dies from suspected poisoning upon her arrival at the castle, all eyes turn to Ada.

As suspicion and tension rise, Ada must prove her innocence and her worth. Can she navigate the treacherous intrigues of the clan, earn Lachlan's trust, and fulfill her destiny? Or will the shadows of her past and the secrets within the castle destroy everything she has fought for?
