13 Things That Don't Make Sense - by Michael Brooks

Each chapter of this book covers one of the 13 "anomalies". It is written like a novel, in that each chapter wraps up with a "teaser" to get you starting the next. It is well written, with enough detail for the scientifically literate reader, without the need to be an expert. Although it was largely about what we don't know, or are not certain about, it left me feeling optimistic and enthusiastic about science. All in all, a very good read from which I learned lots of interesting stuff and got plenty of food for thought.
