Good to have for those of us who cannot get the whole story. In addition, there is an interview that answers some questions. A great bonus on DVD. Thank you.

Ex Output:
Good Review


Ex Input:
This book did not have much helpful info. It was basically about getting a horse to do anything. She had way too many tips on how to train your horse. There are ways in which all three children can learn. I found myself skipping over those parts because the information was nothing new. Not worth buying.

Ex Output:
Bad review


Ex Input:
This is my first book review and I am quite surprised at how disappointed others were with this book. I've read many books on this subject in the past 20 years, including works by Michael Collins, Peter Kuznick (Who's Afraid of Red Riding Hood?) and even Andrew Wakefield. A lot has changed with respect to vaccines and our vaccination status today.
