Finn O'Reilly should have died in the crash. Instead, he woke with a silver arm that breathes, burns, and remembers battles from a time when gods still bled. Everyone calls it a miracle. Finn calls it a curse.When Fomorian sea-demons crawl out of legend to snatch his sister Orla, Finn learns the truth. His new arm isn't a prosthetic. It's Nuada's ancient weapon, a shard of the sword that once chained Balor the One-Eyed. The Fomorians want it back. The gods want their debts paid. And prophecy has already marked Finn as the heir to a war he doesn't understand.Dragged into a hidden Ireland of god-born warriors, angry druids, and trickster crows with too many opinions, Finn has two choices. Fight for a legacy that terrifies him, or lose Orla forever.The Silver Hand of Tara launches the epic Silver Hand Saga with a clash of myth and madness. Fans of Rick Riordan's Celtic myths and Neil Gaiman's dark magic will tear through this first chapter in a saga where prophecy isn't destiny, it's debt, and someone always pays in blood.
