Recently in my job I encountered the following on the back of a book:
The pace of change in work with these client groups continues and there is a call from busy workers to be kept up-to-date with all the new developments in theory, research and practice. This book offers them signposts to help them refine or extend the range of available intervention options. [The editor] has brought together an international team of respected authors to consolidate knowledge on a range of topics and to further stimulate debates. Their contributions are organised into themed sections that address theory and research development; engagement of young people; assessment issues; practice issues; management issues, treatment issues and outcomes. The text builds on [the editor]'s previous works ([XXXXXXX XXXXX] Publishing, 1999; 2002) by using the material as building blocks to chart how things have evolved further, been disregarded or replaced by new ideas, or been refind and developed further. As our state of knowledge accelerates, and narrows our ignorance gap, the need to transfer the progress into practice becomes necessary. This text acts as a vehicle to achieve this goal.
I defy you to tell me what the book is about. Without the title, that blurb is entirely useless. Even when you know the title (which tells you the book's subject), the blurb is remarkably free of information.
Any guesses on what the book is about?
