This was a really fun one. Sigrid has grown up with the Valkyries but has never been one of them. She accidentally sees a prophecy involving herself on Sleipnir, Odin's mount, and leading an army from Helheim. But how on earth is she going to get to the mount? 

To find answers, Sigrid travels to retrieve the missing relic, and the horse from Helheim herself. With Miriam and Fisk, they make an unlikely band of travelers. As Sigrid progresses, she learns about her last, her heritage, and has an important decision to make about her future.
