This book is an excellent resource for any clinician interested in learning more about acceptance and commitment therapy. The authors do a great job of explaining PTSD from an ACT perspective, emphasizing the verbal nature of PTSD and its experiential avoidance component. What I found most valuable is their presentation of each of the core components of ACT, and the use of transcripts from actual sessions to illustrate each component. Well-written, engaging, and very practical. It even has cool illustrations!
