I grabbed this one out of the re-read pile to fill in time while I try to figure out what new book I want to read. I have read this one a couple of times already but not in the past five years, so it was time to trot it out again and give it a listen. Author Jeffrey Kluger is in the business of making science and recent events in the science world accessible to non-scientist (like me). He wrote this book in celebration of the 50th anniversary of the development of the polio vaccine in 2005. It is a well-crafted story that combines biography, history and even a little science. If you haven't read it yet, I do recommend it.
