From the acclaimed author of HOME FIRE, 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 if 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?
