Say, do any of you know good kids' books about fear of being misunderstood or trouble adapting to a new situation? Something along the lines of Elephant and Piggie would be perfect, but anything up to about middle-grade will do. Either non-fiction or a fictional treatment of something like moving to a new school that is very clear about the emotions involved and the coping mechanisms used, with a happy ending.
