A lot of feelings and emotions are discussed, but I feel like I wanted more details. For example, how many of Hanna's friends knew about her affliction? How do you tell someone something like that? What was day-to-day life like? How did she cope with losing time? How did Hanna find out she had DID, and what was her reaction? What was Rachel's reaction?

One other question that really nagged at me was, what happened to Catherine? Catherine is the birth name and "host" to the body, before the other personalities were created. Does she still exist within the system? Or did the system essentially kill her off?

There is a lot of repetition in this book. Rachel is constantly repeating things like "I had to teach Hanna how to trust" or "Hanna didn't realize it wasn't normal to not sleep." A few times for emphasis is fine, but it did become excessive. Also, Rachel uses the phrase "the dictionary defines..." far too frequently. Defining words as a segue are so cliched it feels like a cop-out.

Beyond These Walls is a fascinating account of a fascinating affliction. It takes a strong stomach to read the accounts of abuse, but the successful integration of Hanna's fractured personalities into one whole psyche is a worthwhile journey.
