I think either A Time to Kill or The Client is my favorite Grisham book, but it has been a very long time since I read either one.
Foreign Influence by Brad Thor
A much better book than The Apostle, as this book is about Harvath trying to connect the dots between the bombing in Rome and a hit-and-run attack of a woman in Chicago, and prevent from further terrorist attacks. I worried at first, the 2 separate storylines would be like The Apostle, but this one is done a lot better.
Kitchen Confidential: Adventures in the Culinary Underbelly by Anthony Bourdain
Basically, the story of Anthony Bourdain's career as a chef, and the behind the scenes stuff of the restaurant business. It can be unpleasant and intense at times to read, and for me, enough not to think about being a chef. Definitely worth checking out for Bourdain fans.
