The Ash-Born Scion

I've spent my life as Kazimir Leskov, a nobody, raising my little sister, Lena, on scraps and kindness in the grimy streets of Port Raskov. My only hope was my girlfriend, Anja, but her family saw me as dirt. At a dinner meant to be my salvation, they humiliated me, casting me out. But as I stumbled into the rain, a fleet of black cars surrounded me. My family had arrived. They are the Voronins, a dynasty of clandestine superhumans who manipulate reality through 'Echoes,' and I am apparently their long-lost heir. They whisked me away to a life of impossible luxury and power I never dreamed of. But there's a chilling secret buried in the family's past: the real Kazimir Voronin died as an infant. I am a duplicate, an echo created to fill his place, and my newfound power is just a fragment of his. Now, I must master these ghostly abilities to protect Lena from a family that sees us as tools, all while my cruel 'cousin' Zoya circles like a vulture, eager to expose my secret and claim the inheritance for herself. How can a copy prove he's worth more than the original?
