Fall is in full swing, for better or for worse. The advantages: football! And being able to walk outside without immediately bursting into flames. The disadvantages: allergies! And having to hear the phrase “pumpkin spice latte” 5,000 times a day. Luckily, this month brings a lot of great books you can read in between trips to the basement to retrieve your boxes of sweaters. The best books of October include a biography of one of America’s most infamous mobsters, mystery novels set in Los Angeles and Dublin, and a fascinating look at America’s haunted places.
