The Big Sleep by Raymond Chandler: The Philip Marlowe books are quintessential noir, with all it apparent flaws of this time period. And Marlowe is such a great character.
War and Peace by Leo Tolstoy: Since we are allowed to name classics, this simply has to be on the list.
Blitzed: Drugs in Nazi Germany by Norman Oehler: The fascinating account how all of Germany was on drugs throughout WWII.
The Blind Assassin by Margarete Atwood: A wonderful story of two sisters in WWII times. Even though I´m a bit fuzzy about the details of the plot (have to reread this book), I still remember how it made me feel while reading it.
The Orenda by Joseph Boyden: A book about first nation Canadians and their struggle with another tribe and the Jesuit priest, who try to convert to Christianity. As this might suggest, this book is incredibly brutal at times, but it is also absolutely amazing.
The Prestige by Christopher Priest: You will finish this book without having the faintest clue what you just have read. It´s so good, though.
In Cold Blood by Truman Capote: I´m comparing every true crime book that I read to this one and not a single one has even come close to Truman Capote´s masterpiece.
The Perfect Storm by Sebastian Junger: The first non-fiction book I have ever and still one of my favorites. The second part of the novel is an edge-of-the-seat reading experience.
The Name of the Rose by Umberto Eco: I don´ think this has been mentiones by anyone, but this simply has to be on the list too. I even enjoyed reading about the page long description of the door fresco.
