This reverse gap dominant kink story has all the makings of a good tale. She's at first reluctant to engage with whom she perceives as too young to be with her, but he convinced her with his dom side and so much care. The surrounding characters made the book. The love they showed for both Salt and Pepper was a perfect compliment to the story. 
If you are into light BDSM with plot, this book is for you. It's not to say it doesn't get intense, but it's not nearly as heavy as other reads in this sub genre.
