I don't know how old you both are or if you are female or male it matters not; but to me, what does matter is the female character in the book is forced to do something against her will: always. Yes she learns to accept it but no one should give up their dignity and soul to another. This book is physical, sexual and emotional abuse not love.
If you like BDSM, then that is love. If it is forced, that is wrong. In this book it is forced. As for the author, I am not sure who needs the therapy. Erica Lewis or her husband. Pardon me madam, but if you do not want your boys to read it, perhaps because you know in your heart this is not the way to treat a woman, DON'T WRITE IT. Lead by example. Your mother privileges should be revoked because even in your interview you said you were afraid Child Protective Services would be coming to knock on your door. Why would you make such a statement if you really felt in your heart this was a nurturing thing for a mother of two to write?
Treat your partner kindly -- You are my candy boy and you have me wanting you -- I'm your Venus, I'm your fire .... much kinder. --- :)
