"Child of Our Time" by Michael del Castillo is my favourite book about the Holocaust. It is a semi-biography of the author's experiences in a concentration camp---not because of his race or religion, but because of his mother's politics.
I feel it is a book that seems to be overlooked to often. If you have not read it & can find a copy it would be well worth your while.

When internet searches first became available for books it was the first book for which I hunted. Before then it was impossible. It could only be found in libraris, having been published in 1958. ( )

Tanguy is a gripping story, but unfortunately a real one, relating the life of a child --his own life in the end-- who run away from Spain to France after the war, for being deported to a concentration camp, first in France and then in Germany. Abandoned by his parents, in part due to the cirmcustances, he became an adult quite fast. His sorrows tought him not to hate and judge people, he has understanding almost for everything, while slowly he is becoming more and more apathetic, to the point that he would have left himself dying in a couple of occasions. His story is also somehow the story of Europe, the horror of wars, the fate and the sorrows of people, who are no longer behaving as human beings, just fighting against fortune to survive. A sad and tough novel, an awesome story worth to be read. The style of Michel del Castillo is clear and concise. The prose is quite good.

Una vez más las guerras varias que azotaron Europa. Pero a través de los ojos de un niño, que apenas sí tuvo tiempo para serlo. Tras embarcar para Francia con lo puesto, cuando la Guerra Civil tocaba fin, Tanguy, que no es sino Michel del Castillo, narra con demasiado realismo el abrupto camino que le tocó seguir, si bien, en ningún momento elegir. Sobre todo me gustó bucear en lo complejo de una personalidad, que se forma entre miserias, campos de concentración, hambre, desprotección, pero sobre todo mucha soledad. ( )
