In 2015, journalist Carla Power published If The Oceans Were Ink: An Unlikely Friendship and Journey Into the Heart of the Quran, which chronicled her friendship with a madrasa­-trained sheikh who lead her through a deep reading of the Koran. That book was a finalist for both the Pulitzer Prize and the National Book Award. In her new book, Home, Land, Security: Deradicalization and the Journey Back from Extremism, Carla confronts some of the questions she hadn't engaged with in the last book, namely what draws ordinary Muslims into violent extremist groups like Isis and Al Qaeda and how reliable are the roads back? Through dozens of interviews with ex-jihadis, their family members, and those who seek to rehabilitate them, Carla connects the dots of a constellation of reasons and motivations to join extremist groups. The patterns that emerge are both surprising (in one case an entire extended family was lured by the promise of a better life in the Islamic State) and all too familiar (social media plays a role, no surprise). Carla, an American who spent much of her youth in the middle east, spoke with Meghan about what her reporting taught her about human loneliness, cultural isolation, and youthful impressionability. Moreover, she explained how what's commonly referred to as the "Islamic world" is in fact many worlds, each with its own characteristics and complications.
