My opinion of this book is I HAVE NEVER RECEIVED IT, AND THEREFORE CANNOT GIVE IT A REIVIEW! Perhaps amazon can refund my money since the product was never sent to me. THis is the third time I have complained, and STILL I HAVE RECEIVED NO COMMENT FROM AMAZON---THEY ARE APPARENTLY NOT CONCERNED AT ALL WHEN ONE OF THEIR CUSTOMERS IS RIPPED OFF. I HIGHLY RECOMMEND THAT YOU SHOP ELSEWHERE.
