An illicit encounter with the Spaniard…

A year later, she learns that Cortez is the rightful successor to her adoptive father's fortune, and penniless Elin finds herself at risk of losing everything—including her son! 

Cortez Ramos is set on claiming the secret Elin kept from him—but Elin proves as protective a mother as she is a torturous temptation. His solution: demand a marriage of convenience, which will legitimize his heir and return Elin to his bed!
