After Nadia's violent mobster ex-husband goes to prison, she enters the Witness Protection Program, but she doesn't trust the government to protect her. She signs up to become a mail order bride to a Vaxxlian, hoping to move far, far away out of reach of her vengeful ex. But when Rozar arrives to claim her, she's hesitant to leave with him right away, wondering what kind of mate he'll be, if he'll turn out to be like her ex. Once bitten, twice shy.
Rozar is a nice addition to the Intergalactic Dating Agency series about human women meeting their alien mates on Earth. You have a strong, protective, doting alien hero, a younger, sweet heroine in need of protection, a villain who threatens their romance, and then an HEA.
