The subject of submission is one that is controversial and that a lot of people misunderstand. This book does a pretty good job of explaining what submission actually means, and more importantly, what it does not mean. I find it hair raising that anyone would use Ephesians 5 to justify a husband's physical abuse of his wife, but the fact that the author feels the need to make this explicit means there are clearly people that do. This has to stop!
One thing I would point out, one of the points that the author makes is incorrect. She claims that Genesis 3:14-16 gives women the power to crush Satan. The passage, as any Bible translation will show even on a cursory reading, is that this power is given to the offspring of the woman and that He will be the one to crush Satan.
