They decide to unite their efforts to claim her. With all three of them on the job, they can't possibly fail to attract her to them. But none of their attempts to get to know her better succeed. First they take her to a waterfall, but she's wearing a swimsuit under her clothes so they don't get to see her body. Then they meet strangers on the mountain who are planning trouble for their Alpha, so their date is cut short as they rush Kady out of danger and go to tell the Alpha what is happening. With various Alphas fighting to be the Supreme Alpha of Europe, will they ever find time and safety to romance Kady properly? ** A Siren Erotic Romance
