I read all three books because of the huge conflict they caused among friends. I agree with CC Bride. They are soft porn and I do not recommend them to Christians, especially those who are impressionable.
A lot of the information I found on websites was incorrect, so here is a brief summary:
A 27 year old man was abused initially by his mother’s (who died after being involved in drugs and prostitution) “boss” (don’t want to use that other word in a Christian forum), and by a friend of his adopted mothers, and was introduced by the older woman to BDSM [Bondage and Discipline (BD), Dominance and Submission (DS), Sadism and Masochism (SM)] at the impressionable age of 15. It consumes him and he is unable to have normal relationships with women.
He meets and falls in love with an innocent/virginal recent college grad (age 22 – not a child as it says on some websites that accuse him of pedophilia), and attempts to introduce her to this lifestyle.
I’ll skip over the graphic details and language of the book to the end: The woman he loves and his adoptive mother convince him that he was abused by the older woman and that his behavior is not normal, and a healing of sorts takes place. He marries the woman, they have a family, blah, blah, blah.
The most offensive thing I found about the books was not the sex, but the idea of chaining someone to a cross. As a Christian, I simply could not force myself to read that part.
