Sold To The Ruthless Alpha

Alpha Damien is a multi-billionaire. He's a mafia and a strict
businessman. He runs a lot of businesses and also gives loans to
people... if you can't afford to repay your loan, he collects
whatever he wants to take from you that is equivalent to the loan.
He's a ruthless and fearless Alpha, but he finds out his mate is the
daughter of his own of his debtors, and she has lived all her life as
a nun... How would a nun satisfy a ruthless Alpha???
