Hidden Heiress, Contract Nanny

Seven years ago, Natalie Cross signed a contract to save her sister: work as a nanny for billionaire Dorian Valmont, and he would pay the medical bills. Now, days before the contract ends, Dorian brings home Tiffany — the girl who bullied Natalie and left her sister in a coma — and hands her over as the prize of a bet.

What Dorian doesn't know: the international deal he is desperate to close is Natalie's to sign. And the man coming for her is the one the underworld fears as the Black Emperor.
