The Desert Prince's Convenient Bride (Harlequin comics)

A private jet lands in the Australian Outback town where Hannah works as a doctor. Her visitor: Sheik Marik, ruler of a faraway Arabic kingdom. According to him, Hannah's six-year-old nephew, Mickey, is next in line for the throne—and this barren land is no place for a future king. He’s here to take Mickey away! Mickey was thrust into Hannah's care by her younger sister, and she's loved him like her own ever since he was an infant. So she can't let him go! What will she do when she's told that the only way for her to stay by her dear Mickey's side is to marry the sheik?
