On 17 October 2013, Sadiq and Sara Juma experienced one of the worst things that can happen to a parent. Their two teenage daughters, 19-year-old Ayan and 16-year-old Leila, left the house as usual in the morning, but never came home. That evening, their frantic parents received an email from the girls, explaining: ‘we have decided to travel to Syria and help down there as best we can… Please do not be cross with us.’ In that one moment, the Juma family’s world shattered. In this impeccably balanced book, journalist Åsne Seierstad tells the story of what followed, as Sadiq desperately tries to get his daughters to come home. She also looks back, drawing on texts, emails and interviews to understand how two young Norwegian women could be so deeply radicalised without their parents even suspecting. It is a very difficult story to read, and it is harder still to emulate Sierstad’s admirable detachment, but I believe it’s an important book: a rare flash of compassion and humanity in a dialogue that seems to have increasingly broken down.
