Looking for a grimdark book

Im looking for a book about dark and cruel gods. Maybe uncaring, maybe actively involved. Not sure. I've been tinkering with Lovecraft works but I recently finished a game called fear and hunger of that's a good starting point. Huge fan of Berserk manga and while I'm not current the betrayed and, honestly, hopelessness I kinda liked. Something bleak. I feel like I'm rambling but I'm hoping this gives a good idea of what I'm searching for. Been trying to find something for a minute know with no avail.
