Legends and New York Times bestselling author Aaron Allston bring you the story of a mortal man and the Viking gods - a story of snowy hells, deception, and death.

In late 1941, writer Jim Langley vanished from his home, leaving behind an unfinished suicide note, taking only his firearms and the clothes on his back.

An Occurrence at Bifrost Bridge  tells the story of that disapearance -  of Mist the Valkyrie, of the horses Ash and Embla, of the Norse gods and the Fenris wolf, and of the mystical superhighway in the sky, the Bifrost Bridge.

An Occurrence at Bifrost Bridge includes author’s notes about the history, inspiration, and writing of the story.
