From Fictiondb:

Hot-shot surgeon Karim Zaraq is prince of a desert kingdom. Karim knows he must find a wife and produce an heir, but this playboy wants one final fling before royal duty beckons.

Pretty midwife Felicity Anderson has no idea who Karim really is, but her one night with the sexy surgeon has turned her world upside down -- suddenly she's pregnant!

With Felicity carrying the kingdom's hopes, Karim must marry her. But Felicity won't say "I do" unless the prince can prove it's for love.
