This is the first entry in the Club B BDSM Club romance series.
Sebastion is a strong and gorgeous athlete and business owner (horse ranch and horse showing). He is a complete novice to submission but realizes his interests and inclinations. And, conveniently, his ranch abuts the property of Club B. Mistress Vivienne has been refusing to accept a submissive for years, only topping at the club.
The story arc that follows is delightful (and, sure, utterly predictable). That attraction is intense. The sex and D/s is subdued compared to other series in the subgenre, but that is OK.
I have some issue with five years of denial about the end of an earlier relationship can be overturned by a ten minute conversation with an insightful friend. But that is, again, a very common trope in the genre. "Aha! It wasn't all my fault! I need to fix this!"
A well-written first book in the series. I will be continuing to read the series.
