Extremely well-written, a joy to read despite the bleak subject. I really cared about Max and his parents. Even the Nazis were portrayed sympathetically, or at least they were not just evil cardboard cutouts. The only question I have unanswered is: the first line states that Auschwitz took one year of his life, and he gave it another four of his own free will -- what does that mean? The book depicts the year mentioned, but not the other four. My wife read this and didn't get that either.
Anyway, a minor point, and really a wonderful book. A shame a major publisher hasn't picked this up.
