For two thousand years, Mike O'Hara has been the Hornet—an immortal guardian wielding the legendary sword Svafrlami, protector of the realms, and keeper of names carved in stone. He has outlived friends, lovers, and entire civilizations, bearing the weight of endless loss with grim determination.

When the ancient Watchers vanish without warning, reality itself begins to fracture. From the depths of the Void emerges Raidon, a nightmarish fusion of two ancient enemies bound together by mutual hatred. This parasitic entity exists across multiple timelines simultaneously, corrupting everything it touches and unraveling the fabric of existence itself.

As reconnaissance teams are obliterated and tears in reality spread across the realms, Mike faces an impossible choice: lead one final suicide mission against an unkillable enemy, or watch everything he's protected for millennia collapse into chaos. But the next generation—Kaelith and Theron, children of his closest allies—refuse to let him sacrifice himself alone.

In a devastating confrontation at the Convergence Point, the ultimate price must be paid. When Maeralya and Ragot make an impossible sacrifice to give Mike his one chance to strike, he must decide whether survival is still possible after two thousand years of war—or if some burdens are finally meant to be set down.

Epic in scope and intimate in emotion, Eternal Blade is a story of immortal warriors, impossible sacrifices, and the courage required to let go of the sword and embrace what it means to simply live.
