Dr. Pederson is a DBT therapist and author, who provides training to various organizations including the Federal Bureau of Prisons. This book is used by Therapists and their incarcerated patients. The illustrations for the books had to be uplifting and take into account that sometimes all an incarcerated person can see is the sky. 

Going through therapy and making changes to your life is difficult, doing this in a prison setting even more so. I hope this book will help people, and I hope these illustrations will cheer them up so they can keep on going.
