The brilliant new thriller from the international bestselling author described by Dan Brown as 'the modern master of the hook and twist'. *** You've lost your daughter. She's addicted to drugs and to an abusive boyfriend. And she's made it clear that she doesn't want to be found. Then, quite by chance, you see her busking in New York's Central Park. But she's not the girl you remember. This woman is wasted, frightened and clearly in trouble. You don't stop to think. You approach her, beg her to come home. She runs. And you follow her into a dark and dangerous world you never knew existed. Where criminal gangs rule, where drugs are the main currency, and murder is commonplace. Now it's your life on the line. And nowhere and no one is safe.
