For the Valkyrja Bryn, there’s only one path to redemption after her sister’s death: find the Ragna-dægr and restore the Alföðr's faith in her. Her plans immediately falter when she wakes on Miðgarð on a bed of flames to find not the promised warrior meant to save her home, but an ordinary mortal, Grayson Hohlt. Months of catastrophic Quakes have destroyed the life Gray once knew. Bryn reveals the Quakes are the first wave in a prophecy dooming both their worlds, and that he is the only one who can save them all. Although he has no idea what he’s doing, he follows her into the unknown. Refusing means abandoning both worlds to their fate.
Ásgarðr is nothing like Gray’s seen before and nothing like Bryn remembers. Bryn has always been able to defend herself. To place the future of Ásgarðr in the hands of someone else, especially a mortal with zero battle training and an unexplained healing power, is unthinkable…yet, she can’t help but see a hidden courage in his determination. Threatened by nonbelievers and forced into the perilous Hryersti challenges to prove his bravery, strength, and loyalty, Gray must either claim the title of the Ragna-dægr or fall back into familiar self-deprecation. With Ragna-røk looming on the horizon, hesitation means death. If Gray proves himself unworthy of the title of Ragna-dægr, he condemns both their worlds. For Bryn, failure means choosing between her heart and the family she’s sworn to protect.
