'This is an important overview which throws much needed light on a hidden social problem. The dilemmas faced by practitioners, services and researchers are sympathetically identified. The overlap between sexual exploitation and other behaviours, such as problem drug and alcohol use, is clearly demonstrated. I welcome the call for more attention to be paid to meeting the emotional and mental health needs of a group of young people who can seem too difficult and challenging. Jenny Pearce shows however that, with exceptional skill and patience, youth workers and others may be able to help stop them dropping out of sight.
