"Taking account of the commercial sexual exploitation of children and young people (male or female - up to age 18) and the selling or 'swapping' of sexual 'favours' for some form of reward, as well as the production, sale, marketing and possession of pornographic material involving children; the distribution of pornographic pictures of children over the internet; and trafficking in children - this book addresses: how these commercial practices have come about; how young people become involved; what subsequently ensnares them; what needs to be done in practice in order to respond effectively to the young people's needs; what we have learned about what should not be done."--BOOK JACKET
