I have binged the MacKenzie Grey series over the last week via Audible and I absolutely love it. I am starting the last two books (Blood of the Wolf and Return of the Alpha) via Kindle as they are not available on Audible yet. There are times when the main character, MacKenzie, is a little annoying with her attitude towards making sure everyone knows she is independent, which causes many squabbles but after the first few books, it gets less annoying and almost turns towards endearing.
