Win the bet. Break the rules. Don’t fall in love.

You are the heir to the Valmond family, born into wealth, privilege, and a reputation that follows you everywhere.

At Manchester University, your name opens some doors… and closes others.

Your stepsister, Kathryn Merteuil, is the only one who knows you well enough to never trust you.

Beautiful, brilliant, and dangerously manipulative, she treats life like a game, and you are her favorite rival.

When Cecile Caldwell, a sheltered girl raised under strict rules, enters your social circle, Kathryn sees an opportunity.

Celice is engaged to a boy Kathryn once desired for herself.

She wants revenge.

She wants to ruin Cecile before anyone else can claim her.
