The Mafia's king Contractual Bride

Kathe, the only daughter of Douglas, a powerful business tycoon who values fame and power above everything else, never imagined her life would change overnight. Sold off by her own father to a secret organization for reasons she doesn't fully understand, Kathe’s only choice is to run away from the arranged marriage forced upon her. But fate has other plans. Instead of escaping, she finds herself bound to a complete stranger—Jark Harley Quinn, one of the most feared mafia billionaires in Washington and France. Cold, calculating, and driven by his own hidden agenda, Jark enters a contract marriage with Kathe for reasons far beyond her understanding. For months, the two are tied together by an agreement meant to benefit them both. But neither of them expected what began as a deal between strangers to slowly turn into something far more dangerous. As secrets unravel, enemies rise, and the underworld closes in around them, their bond is pushed to its limits. With love becoming the greatest test of all, Kathe and Jark must decide whether to trust each other… or let the truth tear them apart. Will their love survive the darkness surrounding them, or will it destroy them both? — Description from novelcodex.org
