If you liked that book, RitalinKid, maybe you should have a look at 'Fateless' by Imre Kertész. The author, who himself has spent a year in Auschwitz, tells the story of a young Hungarian Jew, who is broght to Buchenwald and Auschwitz, too.
Especially the ending is very memorable, for the story is told without vivid descriptions neither is it very emotional until the very end..
Even back there, in the shadow of the chimneys, in the breaks between pain, there was something resembling happiness. Everybody will ask me about the deprivations, the terrors of the camps, but for me, the happiness there will always be the most memorable experience, perhaps. Yes, that's what I'll tell them that next time they ask me: about the happiness in those camps.
If they ever do ask.
And if I don't forget.
