I read the book about 5-6 years ago.It's mostly about using wheels for big 6 digit lotteries.Its good but she also says some stupid BS like hiring an accountant before winning the jackpot.
If you are into wheeling big lottery games advise you to look into Bluskov books .His wheels are much better (same winning guarantees on the wheels as G Howard but with less combinations which means cheaper tickets) I have one of Bluskov books ,used it a few times and hit twice 4 numbers in Florida 6/53 lotto .But I'm not a lucky guy so I don't believe in hitting the Lotto ,Powerjoke or Megajoke.Rather make my own luck with Pick 3.
Just google "Iliya Bluskov" and you'll find his books
