I've been a fan of Xanthe's work for many years now, and the BDSM world has been a favorite of mine. So buying and reading this original book set in that very same 'verse was a no brainer.
Like people before me already pointed out, the book felt a little rushed in places. While I enjoyed the story overall and loved the relationship between Rick and Matt from the very beginning, I felt that the "bad guy" was a little too constructed to be hated and that some scenes weren't a favorite of the author and she rushed through them to be over and done with them as fast as possible. That's a shame because I know she can do so much better.
Still, I enjoyed the book and don't regret buying it. It's still tons better than some other things you can buy out there. And at the end of the day, she wanted to provide a love story, and she definitely gave me that.
Anyway, I hope she'll write more original fiction and won't be discouraged. I know she can make it.
