She was supposed to be free. Safe. But some scars go deeper than magic. After narrowly escaping the clutches of the Death Eaters, Y/n is left to grapple with the trauma carved into her skin-and her soul. Haunted by memories of pain and betrayal, she tries to move on. But one truth refuses to let her go: she still loves him. Mattheo Riddle remains imprisoned in the shadows of Voldemort's world, his fate uncertain. And when Y/n begins to experience strange, painful visions of him-bleeding, breaking, changing-she realizes her connection to him didn't end with her escape. A dark curse left behind by Bellatrix binds them in blood and suffering. But is it a punishment... or a lifeline? Back at Grimmauld Place, whispers of a mole within the Order begin to spread-someone is leaking secrets to the enemy. And with the Dark Mark scorched into her skin, suspicion quickly turns toward Y/n. As her family begins to doubt her loyalties, Y/n is forced to navigate a world where no one fully trusts her, and the boy who once did might not survive long enough for her to reach him. As Voldemort grows more ruthless, using Mattheo as bait to lure Y/n back, she finds herself caught in a battle between duty and desire, light and darkness, healing and destruction. With betrayal tightening around her like a noose, Y/n must decide: is saving Mattheo worth risking everything-even the world? A story of forbidden love, shattered trust, and the magic that binds us-"Bound By Blood" dives deeper into the darkness, where love is a weapon and sacrifice is the only salvation.
