Query: Caution

Beware: A full HALF of this book is written like a novel... and a cheesy, awful one at that.Borderline Personality Disorder Demystified (Friedman et al) was far more informative and respectful. And Borderline Personality Disorder for Dummies, despite its unfortunate title, was also excellent; very complete and easy to read.
