Princess Adaline is the eldest daughter of King Cassius and Queen Lilith of the kingdom. To the court and the people, she is known as the perfect princess — graceful, kind, gentle, and charitable.

But that is only the mask she wears.

Behind closed doors, Adaline is far more calculating than anyone realizes. Growing up under the rule of her cruel and controlling father and alongside her volatile older brother, Prince Lucian, she learned very early that kindness alone does not survive in a palace like this.

So she adapted.

Adaline became observant. Careful. Quietly ruthless when she needed to be.

She learned to hide her true thoughts behind polite smiles and soft laughter, analyzing everyone around her as if they were pieces on a chessboard. While the court sees a sweet princess, Adaline secretly operates in the shadows, working against her father’s rule and manipulating events from behind the scenes.

When Princess Raven Blackwell arrives from the kingdom of Valeria — supposedly to marry Prince Lucian and secure a peace treaty — Adaline immediately notices that something about her is... wrong.

Raven is too careful. Too quiet. Too controlled.

The guards watch her like she might explode at any moment.

And that makes Raven the most interesting person Adaline has met in years.

At first, Adaline approaches Raven out of curiosity and suspicion. She wants to understand her.

But as the two begin to interact, the line between curiosity and affection slowly begins to blur.

What Adaline does not yet realize is that the quiet girl her brother is meant to marry may be just as dangerous as she is.

And the worst part?

Adaline might be starting to like her.
