I'm a long time Joey Hill fan, but this is the first book I've read in her "Vampire Queen" series.
Kaela's a powerful vampire, but she's fundamentally a submissive, and the dissonance between who she is and who she has to appear to be is tearing her apart. She accepts an invitation to the mysterious Eden resort island that promises to fulfill her deepest wishes, where she meets Garron, one of the staff Masters, who will be her guide on her journey to true, but temporary, submission. It can't be permanent -- other vampires would kill her quickly if they sensed any weakness. However, as Garron reveals the beauty of allowing him to be her Master, Kaela dreams of the impossible -- bringing Garron back with her to be her servant, but also her Master.
Hill writes extensively about Kaela's thoughts and feelings as she struggles with the fight between her vampire nature and her true submissive self. So... there's a lot of navel-gazing. And while it certainly vividly illuminates the D/s dynamic, it can get a little circular...and honestly, I struggled to get through some it. But later on the story picks up momentum, and it's great when Kaela has to make the ultimate submission -- allowing Garron to choose his destiny.
So..while I'm not generally a PR fan, and mostly stay away from vampire/werewolf stories, this one was definitely a worthwhile read.
