The Weight of The Shards

Kaelen was born a mountain, but he was raised to be a shield. For twenty years, he served as the "token monster" sidekick to the world's most beloved hero, Caspian-the Golden Son. He gave his strength, his silence, and even a piece of his own soul to keep Caspian's light shining.
​But when Kaelen finally asks for his freedom, the light goes out.
​In a single night of calculated cruelty, Caspian destroys everything Kaelen loves, leaving him with a "Denied" stamp on his future and a necklace of shattered obsidian that used to be his sister's spirit. Labeled a rogue beast by a corrupt Association, Kaelen is ready to let the rain bury him.
​Until a voice from the gutter speaks up. Jax, a cynical hacker with a grudge against the heavens, doesn't see a monster-he sees a man who has been used as inventory. Together, they embark on a slow, jagged path of vengeance. Not to save the world, but to tear the mask off the man who thought he could own an Oni's soul.
