The concept of the book was interesting and thought some part made me grit my teeth, until I reached the last chapters, I liked this book and was going to rate it 3 stars. I'm sorry, but in the last chapters I couldn't match what was said with what was done and that really spoiled the book for me.Also, I don't know if it's me who missed it but, whether in the BDSM club or the Academy, I didn't see any safe words.
