For the Love of Clover by Shannon Gilmore

“There certainly wasn’t anything between Clover Dunhurst and Hugo Darrington except an inappropriate conversation before a fountain, a search for a private garden, and a quick lesson in how to throw a punch.
No. Nothing but that.”

When a reckless wager is placed at Brook’s on Lady Clover Dunhurst’s virtue, Hugo Darrington can’t resist getting involved. After all, Lady Clover is the sister of his business partner, the Duke of Kingsley. Darrington can weigh the risk and set the odds for any investment except one: a forced marriage to a woman who plays chess alone and demands answers to the most wanton questions. She was nothing he expected and everything he needed.
With a duke for a brother and a legacy to uphold, Clover Dunhurst was groomed to avoid any impropriety. However, at a weekend house party, her life takes an unexpected turn when she finds herself caught in a moment of intrigue with the dashing Hugo Darrington, a man as formidable as the marble statue she was admiring. Soon, she’ll be embroiled in an impossible scandal leading to a forced marriage to a man who dared to set the odds on her virtue.

In the game of love, sometimes the risk is worth the scandal.
