Query: Hard to put down

Though I think by most standards I took a bit longer to finish the book, I did finish it within about 5 days reading a few hours a night. If you're fascinated by the morbid and unsettling draw of forensics, this is the book to read. I have to say, after reading "Stiff", I now have a different view of what death ultimately holds for us all. It doesn't have to be the end. The book itself is very easy to read and is quite enthralling - to the point that I lost sleep those 5 nights I was reading it.I gave it 4 stars mainly because there were sections in the book that were a bit dry and slow, but I tend to enjoy the more morbid details when it comes to this topic. Regardless, I highly recommend it.
