There are a lot of books that can help, but it takes more than reading to heal. You have to do the work, and it isn't easy to heal from trauma.

One book you might look for is "Healing the Child Within" by Charles Whitfield. He has a workbook too, "A Gift To Myself." The workbook is meant to take a few years to go through. You will find many other books if you look for them. The thing to remember is that they work, but only when you do the work and don't take shortcuts. If you ask, your T might help you work through one of these books, or might have recommendations for books too.
