Voices from the Walls

What if you suddenly learnt that you are not the person you always thought you were. If your parents, your traditions, your religion, even your bloodline was not what you expected it to be. 
Alec, a Jewish young man found he was not really born as a Jew, but actually he is the son of a German Nazi Officer. 
Voices from the Walls is an historical fiction that tells the story of Alec Rosenthal, a brave, intelligent Jewish boy whose father is sent to a concentration camp in the dawn of the discrimination and persecution campaign against the Jews in Nazi Germany. He is separated from his beloved mother Elsa when he is sent to the Netherlands along with his sister Hannah, in a desperate move to escape the persecution and save their lives. 
Alec is shocked when he finds that he was actually adopted by the Rosenthal family. His natural mother was a German maid who worked for the Rosenthals before the Nazis took over. 
His aim in life now is to find both his foster mother and his birth mother, and to take revenge on his enemies.
