I recently read this book (I know, a little late) and thought it was a great book that cleared up a lot of things I found confusing in other books about AA( a lot about her claim with the little details, languages, memories, who she "recognized" from her past and when, was confusing precisely because it didn't add up to a coherent whole), and that clearly shows she never could have been Anastasia, and why.It seems to be the last word on the subject to me.Then again, the meaning of Anastasia's name was Resurrection, a name that fitted AA as well (even though her real name was the more prosaic Franziska).
