This is a good BDSM series. It has a mix of differnet tings. It is not a series that each book is about a different person Nora is in all of them. Here is the reading order according to Tiffany:
I have so many novellas and free stories that it can get confusing. Let me clear things up. Note, you do not have to read the books in this order. This is merely my suggested order.
