This book was intense for me, in the best way possible. It follows a boy named Gregor who is a Jew hiding in a cave in the forest, he meets a stranger with no name, so he gives him his name (Gavrial). It follows Gregor afterwards while he is hiding and fleeing from soldiers and police, making comrades in other forests. I was experiencing real anxiety over his safety and that of his friends. I cannot recommend it more if you want to be disturbed.
