On a spring evening in Istanbul, Peri is on her way to a dinner party – a night of luxury a far cry from her upbringing. But when her handbag is stolen her world shifts violently. She starts to doubt how she got here: a traumatic Istanbul childhood, student years in Oxford, the rebellious professor who led her and best friends Shirin and Mona to question everything – Islam, love, life, even God – and the scandal that tore them all apart. Over one desperate night she tries to make sense of a past she has tried to forget – but can we ever escape who we once were? Shirin, Peri and Mona, they were the most unlikely of friends. They were the Sinner, the Believer and the Confused.
