Long ago, twelve knights and their king were given extraordinary powers...now their descendants have inherited these powers and the world will pay.

Molten Iron begins in the aftermath of a nuclear explosion in eastern France, killing hundreds of thousands of people, yet no one knows the culprit and a cold war is brewing. Savannah Hamlin is more worried about escaping from the violence done unto her family by the fiery powers she cannot control. Rajeev Patel is oblivious as well, instead focused on providing for his dying wife by insidious means. One similarity bridges them: they are both descendants of the Knights of the Round Table, and through a spell cast long ago, they inherited powers that have leveled cities. While Savannah sets out on a quest for repentance and Rajeev for revenge, they are stalked by servants of the shadows who are both merciless as they are efficient and face humanoid monsters that have impenetrable skin and strange dragon tattoos. Neither realize they are just pawns in a century-long plot that may throw the world into chaos unlike it's ever known.
