Shadow Heiress

To the world, the Sterling family is a portrait of suburban perfection. But behind closed doors, Silvia is a ghost in her own home. Since the "car accident" the sterling family told her about her biological parents , she has lived as a live-in servant for her adoptive family, funded by a secret trust they've bled dry for years.
While her adoptive sister, Maya, lives a life of luxury and steals Silvia's fiancé on their very wedding day, Silvia's three adoptive brothers treat her with cold indifference, viewing her as nothing more than the help.

Everything changes when a fragment of news reaches her through a cracked kitchen door: The nation's wealthiest dynasty is offering one billion dollars for the return of their long-lost daughter. Before she can hear the details, the channel is flicked away-and Silvia is kicked to the curb on her 19th birthday with nothing but the clothes on her back.
Collapsing from exhaustion on a rain-slicked roadside, Silvia expects the end. Instead, she is found by a mysterious stranger with a powerful name and a grudge of his own.

He doesn't just offer her a hand up; he offers her a ring. Together, they will return to the city not as victims, but as the nightmare the Sterlings never saw coming.
The debt is due. And Silvia is coming to collect.
