A richly rewarding and insightful exploration of the psyches of those who have, for one traumatic childhood reason or another, protected themselves from others and the world by withdrawing inside a shell, or hiding out from feelings, and so on. Truly worth the reading (and the work) if you've ever found yourself turning away, being defensive, wanting to crawl into a hole and hide, or feeling overwhelmed by the psyches of those around you. Insights on every page.
