There was a review of the latest novel in The No. 1 Ladies' Detective Agency series in the New York Times today.
These are terrifically enjoyable books. I highly recommend them. They're often classified as "mysteries," but don't be fooled. They're not really.
Unfortunately, the review gives away some of the plot points in some of the books. Not major ones, but if you want total surprise, don't read it.
Next on my list, after I finish Moneyball by Michael Lewis, is A Suitable Boy by Vikram Seth. I've heard really good things about it.
