The author has carefully crafted the narrative and presentation of material to ensure that it is practical and relevant whilst building to an accurate and sophisticated understanding of clinically applicable research.  This is achieved through a crystal clear explanation of the fundamental principles of the entire range of research and how these can be applied to improve CBT practice and therefore to benefit those seeking help.
