I could not get through this book despite several tries, because the story us interrupted by almost-full chapters of discussion on psychiatric research. The authors tell us about the history of mania, bipolar disorder, depression, hoarding, the city where Diehl was born, and on and on, dropping any threads that might tie together a narrative until I just gave up. She’s definitely an interesting subject, and do is psychiatry. but a book has to confidently lead us to some conclusion, or, lacking one, stick to a narrative. This book does neither, leading me to believe that these authors didn’t really have anything to say, but the publisher wanted to make some hay off the recent documentary. Too bad.
