Troll

Years ago, Fortune gave up on his daughter, Sophie, after a troubled adolescence. Now she's gone missing, vanished without trace. And after weeks of investigation, the police have given up on her, too. Driven by guilt, and a determination to atone for his failures as a father, he takes on the search himself. He soon finds that his daughter had been living in fear of a vicious online troll who seemed to know far too much about her. Could Sophie's disappearance be linked to this unknown predator?
