Nietoschka Nezvánova by Fiodor Dostoievski
Dostoievski has that "thing" that always makes it impossible for me to drop the book.
The sadness gets to your soul. The melancholy, loss, loneliness, in other words, life itself are narrated in a way that you feel for the characters.
Just like White Nights, Nietoschka Nezvánova moved me. As usual totally recommendable.
I can't wait to read more of his works.
