This book is very explicit - probably 80% of the book; and not vanilla situations either. It reminded me a bit of "Shades of Grey" with multiple partners although not so much dominance. It was much better written however with well-developed characters. While I cannot imagine ever being in the situations Nina finds, it made for a very interesting read. I should also note that this author must be British as the prose sounds just like our British friends. I would read more books by her.
