4/5 - It took me two months to get through this book, but not because it's bad. My problem was that even though it was interesting...it could be kind of gross. "Stiff" is all about dead bodies: what happens when you donate your body to science, what tests are performed on cadavers to improve driver safety and determine the cause of airplane crashes, a look into the history of body snatching, and even how various parts of the human body were included in medicine (ewww) centuries ago. It's fascinating stuff, but not on your lunch break or as you're eating dinner which is where I normally get a lot of reading time in...hence the super slow pace. 
 The facts are impeccably researched and Roach has a great sense of humor that makes you feel much more comfortable about what you're reading. Even though Roach makes a lot of jokes in the book, she is never rude. Her humor even manages to convey her great respect for the donated cadavers. If you're interested in forensics, anatomy, or have ever considered donating your body to science, this is a must read. My rating is 4/5, but I strongly recommend you don't make the mistake of starting this book on your lunch break like I did.
