Raceball: How the Major Leagues Colonized the Black and Latin Game (Ruck). We all know about Jackie Robinson, but there was a lot more in here that I wasn't aware of.
Freakonomics: A Rogue Economist Explores the Hidden Side of Everything (Levitt/Dubner). Love these guys but had never read their book, until now. Good stuff.
Home Game: An Accidental Guide to Fatherhood (Lewis). Michael Lewis, who deciphered bond trading and sabermetrics, tackles a much more complex topic, that of raising little kids.
Winners Never Cheat: Everyday Values We Learned as Children (But May Have Forgotten) (Huntsman). The elder Huntsman (think Huntsman Hall at Wharton, not his son who recently ran for president) tells us honesty really is the best policy.
The General Book of Ignorance: Everything You Think You Know is Wrong (Lloyd). I love this kind of stuff. Especially good pool-side reading.
Libertarianism from A to Z (Miron). One of libertarianism's main voices breaks down the philosophy from, well, A to Z.
