Five years ago, Kayla Hopper and Prince Arkin Aubosson of Sigotta were patients, along with their spouses, at the same fertility clinic. She is now divorced, and the prince is a widower. A mix-up comes to light, revealing he is the father of her twins. Kayla suggests the only sensible option, a marriage of convenience, but wonders if she can maintain a strictly platonic relationship with the handsome prince, who is still mourning his first wife. Being the wife of the prince is even harder than trying not to fall in love with him when Kayla becomes the target of kidnappers trying to remove her from the royal family permanently.
