American Dervish by Ayad Akhtar
Hayat Shah was captivated by Mina long before he met her: his mother's beautiful, brilliant friend is a family legend. When he learns that Mina is leaving Pakistan to live with the Shahs in America, Hayat is thrilled. Hayat's father is less enthusiastic. Ever wary of fundamentalism, he doesn't relish the idea of Mina's fervid devotion under his roof. What no one expects is that when Mina shows Hayat the beauty of the Quran, it will utterly transform him. Mina's real magic may be that the Shah household becomes a happy one. But when Mina catches the eye of a Jewish doctor and family friend, Hayat's jealousy is enflamed by the community's anti-Semitism - and he acts with catastrophic consequences for those he loves most.
