Marie has always been an afterthought. Her parents treat her like a servant, and her flawless older sister, Anastasia, is the family's shining star. Even at Marie's own birthday party, all eyes are on Anastasia--so much so that no one notices when Marie sneaks away.

But in the quiet of the evening, she has a chance encounter with a captivating man with striking green eyes: Count Kyros. Their brief meeting feels like a dream... until reality comes crashing back. Soon after, a marriage proposal arrives from the count--for Anastasia, of course.

Except... something doesn't add up. The gown that arrives with the proposal? It's clearly made for Marie. Could there be a mistake? Or is this the start of an unexpected love story?
