The moving and surprising story of a lifelong friendship and the forces that bring it to the breaking point Zahra and Maryam have been best friends since childhood in Karachi, even though--or maybe because--they are unlike in nearly every way. Yet they never speak of the differences in their backgrounds or their values, not even after the fateful night when a moment of adolescent impulse upends their plans for the future. Three decades later, Zahra and Maryam have grown into powerful women who have each cut a distinctive path through London. But when two troubling figures from their past resurface, they must finally confront their bedrock differences--and find out whether their friendship can survive. Thought-provoking, compassionate, and full of unexpected turns, Best of Friends offers a riveting take on an age-old question: Does principle or loyalty make for the better friend?
