Hi, I've read Wasted, its a book I'll never get rid of. It actually made me want to improve my situation, as it is an extreme example of eating disorders, and not somewhere I wanted to go, or end up like. I have heard before that others found it extremely triggering. For me it had the opposite effect. Another book I found very good was Bulimia and Binge Eating by Peter Cooper, and Getting Better Bit(e) by Bit(e). These are really aimed at Bulimia though, don't know what your stepdaughter's situation is. It's good that she's started therapy. The road to recovery can be a long and hard one, but the sooner started the better the outcome.
