I don't follow baseball and aside from a single season of little league I've never played the sport so you can characterize me as a lower than casual fan (when I root for a team I'm usually just rooting for the city). Having said that, I really enjoyed this book, which is about baseball but really about conceptions of value. Michael Lewis' writing style is easy and approachable even in the midst of convoluted and seemingly boring subjects (I mean he made baseball statistics interesting, thrilling at times). There isn't an abundance of intellectual rigor here but then I wouldn't have been interested if there were. This is a really entertaining non-fiction beach read that strikes the perfect balance of NPR profundity and opinionated style.
