I've read that book, too, but I don't think her father's side of the story is so much different than the side we're used to hearing. I don't have the same access to information as some fans here do, but according to the book, her father had some kind of companies set up, and when she left home and then turned 18, those companies were in serious jeopardy. Even in the early summer of 2001, when it appeared that things might start getting better between the two of them, he seemed to be concerned about the money issues. If you're in such fragile standing with your daughter to begin with, why on Earth would you bring something like that up? Obviously it is something to be considered, but can't that wait until your relationship is more solid instead of so fragile like theirs still was at that time?
As far as the rest of her family is concerned, it's been widely reported that her brother Thomas and Pierre-Yves Hardenne didn't see eye to eye. Also, according to the book, he had a romantic interest of his own at the time, and was trying to get out on his own a little bit. He says he and Justine were very close at the time, and she took offense when he tried to put some distance between the two of them. It doesn't say much about the other two, except that this past spring, she called her younger sister and suggested that they get together sometime, so apparently, whatever the situation there is, she is trying to set it right. I've also read an article where it says she and her grandparents are on better terms, now, but maybe someone else has more information about the truth/lack of truth in that. I do know that her brothers don't seem to have much hope in rekindling their relationship with her, and they seem quite bitter about it. They say some pretty harsh things about her in that book.
