The duke was known for having only one child, a son who sadly died at the young age of 18. However, Rumours had been spreading around that there was another child, but a bastard. A maid had apparently seen the duke escort a woman from his residence with a baby in her arms. Such rumors always floated around in the talk of the upper-class social gatherings, but it wasn't until much later was the truth exposed. Yes, the great Duke Francis of house De Morée, a handsome, sophisticated man did have another child, but this child's mother was also the late duchess. He announced his daughter, who is a mystery to the aristocrats of Clarines, would début at the next coming of age ball.
The De Morée family have always been loyal subjects of the crown and marriage has always been a desire between the two families. Though, the De Morée household were known for only having sons and so a daughter was always rare, so timings had never been right for a marriage. But will something happen now that duke Francis announced he has a daughter?
With only two weeks until the ball, the rumors and gossip about the unknown Lady De Morée were spiraling.

"She must be a disgrace for her family to hide her from society for so long"

"I heard she attended that famous lady's school in the kingdom of Dayrelia"

"Perhaps she is so hideous the path of an academic is all they could hope for?"

My, how wrong they were.
