What to read after Notes from the Underground?

Notes from the Underground - Fyodor Dostoyevsky - CLASSIC RUSSIAN LITERATURE. The author of the diary and the diary itself are, of course, imaginary. Nevertheless it is clear that such persons as the writer of these notes not only may, but positively must, exist in our society, when we consider the circumstances in the midst of which our society is formed. I have tried to expose to the view of the public more distinctly than is commonly done, one of the characters of the recent past. He is one of the representatives of a generation still living. In this fragment, entitled "Underground," this person introduces himself and his views, and, as it were, tries to explain the causes owing to which he has made his appearance and was bound to make his appearance in our midst. In the second fragment there are added the actual notes of this person concerning certain events in his life.--AUTHOR'S NOTE. Notes from Underground, also translated as Notes from the Underground or Letters from the Underworld, is an 1864 novella by Fyodor Dostoyevsky. Notes is considered by many to be the first existentialist novel. It presents itself as an excerpt from the rambling memoirs of a bitter, isolated, unnamed narrator (generally referred to by critics as the Underground Man) who is a retired civil servant living in St. Petersburg. The first part of the story is told in monologue form, or the underground man's diary, and attacks emerging Western philosophy, especially Nikolay Chernyshevsky's What Is to Be Done? The second part of the book is called "Àpropos of the Wet Snow", and describes certain events that, it seems, are destroying and sometimes renewing the underground man, who acts as a first person, unreliable narrator.
