I like the CBT Distinctive Features series as they provide a comprehensive introduction to some often seemingly complex ideas and approaches. This book on DBT is particularly excellent. The major texts on DBT have been written mainly by Marsha Linehan who developed the approach. While comprehensive they can be difficult to read as someone completely new to the approach. DBT has various different stages and modalities (for example one to one therapy and group work) and it can de daunting to try and figure out how these fit together. The authors, helped by the style of the book series, break down DBT into manageable chunks which help demystify the approach and outline the key concepts.
This book would be an excellent addition to any therapist's bookshelf, whether you are a trainee Clinical Psychologist trying to get to grips with DBT or a more experienced therapist/Clinical Psychologist who wants to know more and wants a short, comprehensive and succinct introduction.
