The Valkyrie Chronicles - Erik Schubach - Bog

The Valkyrie Kara stood alone against the Ragnarok horde on Earth to ensure that the Asgard race and Valhalla could escape. For five thousand years she has fought and evaded the Ragnarok race on Earth, just waiting for her people to return. A human woman, Kate, joins her fight, showing as much conviction and valor as any Valkyrie. Their friendship quickly becomes something more as they hold the line on Earth in battle, to herald the return of the Asgard.
