Twice Finn: The Norse Blade Of Unity

Attention this book is a fanfiction that contains elements of The 100.

When Finn Michaelson, the eldest son of a Viking warrior turned immortal, dies, he expects eternity in Valhalla or at least peace in the afterlife. Instead, he wakes in the body of Finn Collins, a delinquent boy aboard a dropship of exiled youth sent from a dying space station to an unrecognizable Earth. Stripped of his supernatural power and centuries of dominance, Finn must navigate a world that feels both alien and familiar while grappling with the dual identities of a thousand-year-old Original vampire and a seventeen-year-old human.

As the Hundred crash onto Earth's surface, they find themselves in a brutal fight for survival, facing wild terrain, feral creatures, and the shadow of an unseen enemy: the Grounders. Within the group, tensions rise as leadership struggles emerge between Bellamy Blake's fiery charisma and Clarke Griffin's rational idealism. Finn, reluctantly drawn into a leadership role, becomes the fragile bridge between opposing ideals. Using his Viking-born resilience and centuries of hard-won wisdom, he must guide the group not only through the external dangers of Earth but also through their internal chaos.

But Finn's greatest battle is within himself. Haunted by the ruthless power he once wielded and the humanity he now seeks to embrace, he must decide what kind of leader he wants to be-and whether survival requires him to become the monster he once was or the man he's trying to be. As the Hundred face growing threats, both from within and without, Finn learns that leadership isn't about strength alone. It's about unity, trust, and the courage to fight for a future he's only beginning to believe in.
