Keenly intelligent and brilliantly rendered, The Golden Mean is a bold reimagining of one of history’s most intriguing relationships—that between the legendary philosopher Aristotle and his most famous pupil, Alexander the Great.
 
Aristotle is initially reluctant to set aside his own ambitions in order to tutor the rebellious son of his boyhood friend, Philip of Macedon. Still, the philosopher soon realizes that teaching this charming, surprising, and sometimes horrifying teenager is a necessity amid the ever more sinister intrigues of Philip’s court. But as Alexander grows older and becomes a man who will transform the world for better or for worse, Aristotle, like any teacher, ponders his own culpability.

In this final volume of the phenomenal, best-selling trilogy begun with Griffin & Sabine and continued in Sabine's Notebook, the mystery of the two artists deepens, their questions grow more urgent. New obstacles (including a sinister intruder) test the tenacity of their passion, and in each letter or postcard, painting and prose are even more richly intertwined. Destined to be the most sought after novel of the year, The Golden Mean builds toward a powerful conclusion that will satisfy the millions of readers already entranced by the spirited, imaginative, enigmatic union of Griffin and Sabine.

With over 50 weeks on the New York Times bestseller list and one million copies in print, the first two volumes of this unique trilogy have captured the imagination of readers and reviewers across the country.
