Severus Snape Was a Pessimist

With the war gearing up to begin again, the Dark Lord running rampant, and a ministry official wearing (shudder) pink taking over the school, Severus Snape just knows this year will be one of the worst in his life. At least there’s the mystery of the new History professor to keep him distracted. Why does the new professor simultaneously terrify and intrigue him? And what’s with his strange friendship with Potter? Should he be concerned the man might be an assassin? Should he help him?
