Run Away - Harlan Coben

You’ve lost Your Daughter. She’s addicted to drugs and to an abusive boyfriend. You haven’t seen her in six months. Then you find her busking in New York’s Central Park. But she’s not the girl you remember. This woman is frail, filthy, terrified, and in more trouble than you ever imagined. You don’t stop to think. You approach her. You beg her to come home. She Runs. You follow. What choice do you have? And as you descend into the dark, dangerous world she's lost herself in, you quickly find yourself out of your depths. Down here, no-one is safe – and now both of you might never make it out alive.
