Paranormal Romance & Urban Fantasy discussion

I am making a list of books I have read and need some help. I have been using Kindle unlimited so when I return a book it is no longer listed anywhere and I need help finding a book I remember reading. It was about a woman who takes a job as a secretary to try and get proof of her bosses criminal activity. It turns out that a group of shifters are investigating this man and she is two of the shifters mate. It is part of a series because the other shifters I the agency meet their mates in later books but I can't remember the series, titles or author. Please let me know if this sounds familiar.
