Luca Graven, an orphan cursed by poverty, worked under the man loathed the most— Dante Solis. He was a wealthy, powerful mafia leader who had the strongest men, including Luca himself cowering in fear. Unfortunately, Dante took a liking to him. He brought him into his home, enslaved him, treated him like rubbish….but, he never hurt him beyond his limits. Maybe that was why Luca never fully hated him, and maybe, just maybe, that was why he wanted him. Until, a new version of him shows up. He looked exactly like Dante, same voice even, but completely different personalities. This version listened, cared for him, no longer saw him as a mere slave, he nurtured him and treated him like he meant something for once. Of course to Luca, Dante had miraculously grown a heart but that person that showed him kindness and mercy wasn’t Dante. It was Allen Pierce—his doppelganger. Now torn between two different people, yet drawn to each of them and their different souls, he has to make a decision. But they don’t make it easy. Luca wasn’t the only one fighting to choose, they were both fighting to be chosen.
