An unexpected act of revenge will shake the lives of these girls and all those around them, forcing Doña Inés to survive heartbreak and the pain of abandonment. She will also have to navigate the power struggles to make her true daughter the heir to an empire, in an era when women were not allowed to be masters of their own destinies.
