To win their freedom, they must bluff the entire underworld.
You are Lia Park, a card-counting savant whose life depends on the flip of a card and the spin of a wheel. When your brother is kidnapped by the underworld’s most dangerous players, you have no choice but to infiltrate the Valenti syndicate’s glittering Las Vegas empire. Your mission is simple: skim enough chips to buy his freedom. But in the neon-lit shadows of the Obsidian Casino, nothing is ever as simple as it seems. Your luck runs out when you catch the eye of Matteo Valenti, the cold-blooded heir to the Valenti throne. He catches you red-handed, but instead of the execution you expect, he offers you a deal that is far more dangerous. He needs your genius to dismantle a corrupt web of allies from the inside. Suddenly, you are no longer just a thief; you are the secret weapon of the man you should fear most. As you navigate high-stakes roulette tables and narrow rooftop escapes, the line between your mission and your desires begins to blur. Every brush of Matteo’s hand sends a jolt of electricity through you, and every whispered command feels like a promise. In this world of Obsidian Heir, you aren't just reading a story—you are living it. With SideHop’s revolutionary face-swap technology, you can see your own face as the protagonist, making every smoldering glance and heart-pounding confrontation feel intensely personal. This is a journey through the darkest corners of love and loyalty. Can you trust the man who holds your life in his hands, or is he just another player in a game where the house always wins? As the desert heat rises and the bullets fly, you must decide if you’re playing for your brother’s life, or for the heart of the mafia’s most dangerous heir. When the final card is turned, will you be standing by his side, or will you be the one he loses everything for?
