This one had an interesting premise, and the author seemed to understand short story structure better than the previous authors in the series. I don't think both sisters povs were needed though. The emotional connection should have been with the one wanted her memories of her ex erased, but instead it was the cleaner and how he was different from his family. I just wasn't invested emotionally in this or the any of the stories in the series.
I never thought I'd be a fan of alien romance, but Aria has made a fan out of me. This is an alien/human romance where the human is a slave to an affluent alien family of another species. When all the noble aliens are invited to a royal ball where the prince will choose his mate, she's dragged along with her owner.
