I'm reading 'My Life As An Experiment: One Man's Humble Quest to Improve Himself' by A.J. Jacobs at the moment. Its absolutely amazing so far, and I'd highly recommend it, even though I'm only halfway through ;)
A.J. Jacobs is a great author and has written 3 #1 New York Times bestsellers so far. Ive read 'The Year Of Living Biblically' and it was great. Hes worth a read definetly.
