Champion of Her Heart by Juniper Kerry

Smart-as-a-whip Callie has a doctorate in Alien Studies. Unfortunately, her grant money has run out, and with it, her rent money. Desperate for a job, she turns to her high-power father, who has an idea: he will appoint her as the liaison for the Xalke – a race of aliens looking for breeding partners. With his daughter in charge of introductions, Grant Holland knows he can find a way to build new business partnerships. Callie is willing to make connections for her father. …That is, until she meets Prince Dek. Now, the idea of introducing him to beautiful women makes her stomach hurt.

Dek has been sent to Earth with a clear purpose: find female volunteers and bring them back to his planet to breed. Unlike some of his fellow princes, Dek isn’t against the humans, nor is he against babies. When he sees Callie, he knows right away that she is the woman for him. But for some reason, Callie resists. Though she seems to melt when he touches her, she also keeps pushing him into another woman’s arms. Dek has only a week before he must return to his home; can he win her heart in time?
