The PTSD Workbook for Teens is written directly to you if flashbacks, nightmares, or a constant sense of danger have followed you since something traumatic happened. It walks through cognitive behavioral exercises step by step, on paper, so it works like a workbook you fill in rather than something you just read. It costs about twenty two dollars in paperback or twelve dollars as an ebook, no account or subscription needed beyond owning the book. It is not a crisis tool and does not replace a therapist, though it works well alongside one.
