The spring of 1355 brings unexpected changes in Girona. For Isaac the physician, it is time to bid farewell to his student Yusuf, who has become a well-loved member of the family. Yusuf heads to Grenada to meet his real family after they thought him dead for years. Leaving Girona and its problems behind, Yusuf faces challenges of his own as he tries to acquit himself appropriately at the court of his cousin in Grenada. Though he is overjoyed to see his family, two narrow escapes from danger lead him to believe that someone within the castle walls is less than happy about his return. Fleeing for his life, the boy heads for the only truly safe haven he knows. As political, religious, and familial intrigue once again converge on Girona, Isaac copes with the sudden passing of a patient. Now, Isaac must use all his skills and every clue at his disposal to untangle an elaborate web of lies, secrets, and ambition-before another victim is claimed.
