*Clears Throat*
I haven't read the rest of the thread, so pardon my barging in...but here are a few suggestions:
The Reason For God by Tim Keller (studying belief in an age of skepticism)
The Me I Want To Be by John Ortberg (becoming the me we want to be. Self-explanatory, but a good book. One I reference often.)
The Geeks Shall Inherit The Earth by Alexandria Robbins (one of my favorites. Examines students who are labeled "Geeks" and how the same characteristics that cause them to carry the label are the same characteristics that propel them to success in life.)
Freakanomics by Steven Levitt (for us Economics freaks)
Moonwalking with Einstein by Joshua Foer (a study of memory techniques)
Outliers by Malcolm Gladwell (how people succeed in life)
Tempted and Tried by Russell D. Moore (about facing temptations. Very nicely written, might I add)
Too Big To Fail (the inside story of how Wall Street and Washington fought to save the financial system and themselves)
The Pixar Touch (the making of the cinema powerhouse known as Pixar)
A Taste of Irrationality by Dan Ariely (a study of how people make predictable irrational decisions and how the market takes advantage of these)
Blue Like Jazz by Don Miller (one of my favorite books, but I don't know if it's fit for a book club. It's more like a journal).
Erasing Hell by Francis Chan (comes out next Tuesday. Discusses Hell, is it real, what's it like, and why our culture is so adamant on erasing it.)
As you can tell, I have a slight case of ADD when it comes to books.
