I was really looking forward to reading this book for two reasons. First, as someone who studied both Psychology and Child and Youth Work in school, I am used to reading case studies and often found them the most interesting parts of the course. Secondly, MPD is a topic I have always found very interesting and even strongly considered as a topic for my thesis and/or major term papers.
Unfortunately, the actual experience of reading this book did not live up to my expectations. While I found a few of the case studies interesting ("The Stranger Within", "The Evil One", and "A Little Girl Inside" were the ones I enjoyed most), I did not enjoy Ross's writing style. I found most of the book very dry and repetitive, which was a shame because the cases themselves could have been very interesting depending how they were presented. There were also quite a few instances of poor editing, including misspelled words or poor grammar.
One case in particular really killed it for me -- in a case entitled "A Foster Child", Ross very tediously describes all the medication changes the young woman goes through to drive home the point of how badly her case was mishandled. Even though he acknowledges afterwards that it was a long and tedious passage and explains why he wrote it that way, it does not help with the actual experience of reading it. Although I had found the book as a whole hit-or-miss up to that point, depending on how interesting I found the specific case, that section quickly made me lose interest. By the time I got through it (even with skimming the section since I really didn't need to know all the specific names and dosages), I had lost interest in what was otherwise quite an interesting case.
I would still recommend this book as it gives some good, interesting examples of MPD however I would not recommend attempting to read more than 2-3 case studies in a row. Reading more than that only drives home how dry and repetitive the writing can be. It's too bad, because I think the book really could have been fascinating had it been better written.
