Q: As most people readers know, Jack Higgins has written many fine action-packed books. However, this book reads like a twelve-year-old wrote it. The characters are so transparent they could be ghosts.The author and his publishing house must really need the money to rip of the public in this manner. This is the last book I read by this author. One can only rest on his laurels for so long. I'm glad this book was handed down to me or I would have written a really nasty review.

A: Negative
****
Q: The book covers several generations, so with each generation you have to re-learn all the characters. It is difficult to keep track of who's who when every time you get to know the cast, 200 years suddenly pass and we're in the middle of a new crisis. I didn't read the whole series because of this -- it was obnoxious.

A: Negative
****
Q: I was 16 years old the summer of 1969 and remember it vividly. I didn't read Helter skelter until I was 22, when it first came out and learned for the first time many of the detail, and the book truly stays in your mind. That is what most of the other reviews say that it haunts you for many years and you actually feel that you are there on that hot summer night, Sharon and Jay talking in the bedroom and a strange woman walks in and orders them to the living room. How terrifying could it have been for Sharon watching Jay die in front of her and Frykowski and Folger fighting for their lives knowing very well her unborn child and her couldn't defend themselves. Bugliosi wrote with such compassion for the victims and we can truly thank him that these people are behind bars now. Watching Charles Manson talk on television shows how unremorseful he is and will always be.

A:
Positive
