Query: A definite MUST for everyone.

This book has been, by far, one of the best true crime novels I have read, ever. It is extremely well written, and provides all the details a true crime fanatic would want to know about. Pence describes the murder from beginning to end, and gives us an extensive history on John, Michelle, Mary Jean, and even their parents. At times, I could sense my adrenaline rushing, as I feared for Michelle and Mary Jean's lives. I could not put the book down. This is the kind of book you read at once, without putting it down.Extremely engrossing and full of suspense. A must-read for ANYONE. It opens your eyes, and makes you realize how helpless and defenseless one can be, with no one there to help, thinking that Battaglia will not strike again.Well, they were wrong.
