I found this book extremely interesting. I did not Know that such a detailed account of Hitler and Eva's life existed. I read it in two days.
I gave the book 3 stars for one reason: The book is very well written, but in many instances the information reported are not confirmed. In many occasions Infield reports dialogues between Hitler and Eva that happened in private. There is absolutely no chance that those informations are real.
In conclusion story telling in this case wins over facts. This is a shame because it leads you to question the validity of the work itself.
