The Hellion by Christi Caldwell

USA Today bestselling author Christi Caldwell’s Wicked Wallflowers series burns hot as two rivals meet in the flesh and feel the heat…

Adair Thorne has just watched his gaming-hell dream disappear into a blaze of fire and ash, and he’s certain that his competitors, the Killorans, are behind it. His fury and passion burn even hotter when he meets Cleopatra Killoran, a tart-mouthed vixen who mocks him at every turn. If she were anyone else but the enemy, she’d ignite a desire in him that would be impossible to control.
No one can make Cleopatra do anything. That said, she’ll do whatever it takes to protect her siblings―even if that means being sponsored by their rivals for a season in order to land a noble husband. But she will not allow her head to be turned by the infuriating and darkly handsome Adair Thorne.

There’s only one thing that threatens the rules of the game: Cleopatra’s secret. It could unravel the families’ tenuous truce and shatter the unpredictably sinful romance mounting between the hellion…and a scoundrel who could pass for the devil himself.
