Sorry if this isn't news at all, but I didn't know lots of stuff in this book. Just a few things which interested me:
Rineberg received death threats upon coaching the WS - when the news was made public, he received several phonecalls and letters warning him to keep away etc. Apparently Venus, Serena and the rest of the family all received numerous death threats at the start of their careers.
Richard wanted Venus to be a total serve-volleyer at the start. Whenever she was in trouble, he told her to just go to the net and win the point any way possible from there.
After their first meeting, Hingis picked up loads of beads which had fallen from Venus' head during the match - at the press conference Martina was asked what she thought of Venus and her claim she was going to be number one in the world, and Martina gave out the beads to the reporters, laughed, and said she thought it was ridiculous.
(I guess at the time it did seem far-fetched)
Venus seemed to be the far more emotional one of them when they were much younger; she seems to be much quicker with her mouth, a bit more "cheeky" than Serena, and on-court, had the reputation to those who knew her as being more demonstrative with her feelings than Serena.
There's other things, but the general feeling I get is that Richard Williams does not come out of this book well AT ALL; it really sheds a bad light on him. To be honest, the guy sounds like a mad nightmare. However, Rineberg clearly has alot of time for Venus, Serena and Oracene, whom he is clearly very fond of.
It's not exactly a brilliantly written book, but pretty cool to read for a WTA fan.
