Claimed by the Tentacle King

Aria, a socialite who has lost everything to debt, is auctioned off as collateral by her gambling fiancé in her darkest hour. In the chaos she accidentally stirs Casper, an ancient deep-sea monster who believes she is the pearl he has hunted for more than a thousand years. He kills the gambler and carries Aria away to a luxury yacht, where the hidden tycoon keeps her captive and pours a possessive, consuming devotion into her life.
