The Tycoon's Secret Son-in-Law

He controls the world's most powerful shadow capital, but returns home disguised as a worthless son-in-law. Behind the mask of mediocrity lies a financial titan seeking vengeance for his sister's death—and the corporate empires responsible will fall. Bound by a marriage of gratitude, he'll repay his wife's kindness by crushing their enemies and building an empire that makes the business world kneel. They wanted to play him for a fool. Now they'll learn the hard way: in his world, honor is currency, betrayal is death, and he always collects his debts.
