Query: Disregard the only review with 5 stars

If you read the only review of this book with five stars, you will see it is really a one-star review; perhaps the reviewer did that accidentally. His/her actual review explains how awful the book was.I hate to dog on a book, but I've never seen a book with so many disparaging remarks. I want to learn more about the disease I have, from a competant writer. There's even a reviewer who read all the reviews and *still* bought the book, only to give it also a one-star rating.
