The Sound of Valhalla

When Sean Cassidy-mutant, X-Man, and beloved son of Erik Lehnsherr and Charles Xavier-vanishes during a mission, he expects to wake up back at the X-Mansion.

Instead, he falls from a the sky and lands in a land far from his own.

A land of Vikings, longships, blood feuds, gods, and legends.

Stranded in the Viking land, Sean quickly discovers that returning home may be far more complicated than he imagined. His modern clothes, Irish accent, strange technology, ability to fly, and devastating sonic mutation convince many that he is no ordinary man. To the people of Kattegat, the red-haired stranger who rides the wind and can shatter stone with his voice is something between a warrior, a spirit, and a god.

Ragnar Lothbrok is fascinated by him.

Floki believes the gods have sent him.

Lagertha sees a gentle warrior desperately searching for a home.

And Ivar the Boneless sees something no one else does.

He sees Sean.

Not a weapon. Not a demon. Not a god.

Just a young man who has been abandoned once before and is terrified of being abandoned again.

As Sean becomes increasingly entwined with Ragnar's family, his bond with Ivar grows into something neither of them expected. Sean's warmth begins to soften the walls surrounding Ivar's heart, while Ivar becomes fiercely protective of the man he calls his Rauðr Engill-Red Angel.

But Sean's arrival changes more than Ivar.

His knowledge of the future threatens to alter the course of history itself. His powers make him a devastating force on the battlefield, yet Sean refuses to become the conqueror Ragnar believes he could be. He fights only to protect the people he loves.

And eventually, whispers spread throughout the North:

A red-haired angel has fallen from the sky.

His voice can split mountains.

His laughter can shake a hall.

His song can calm the most wounded soul.

And when his family is threatened...

the sound of his rage can be heard for miles.
