Rule the realms. Brynn Aksel is a valkyrie - a battle goddess tasked with protecting both the God of War and the future of Asgard. She fends off giants and dark elves with an iron fist, a glossy smile, and no less than perfekt control. She's focused one-hundred percent on rising through the valkyrie ranks, and not at all on her lifelong crush on Henrik Andersson - the one guy in all the realms who could be her undoing. Henrik serves as War's other bodyguard, and he's too focused on protecting their shared charge to realize that Brynn's a girl. When an unprecedented surge of darkness abducts the Goddess of Love, Brynn's already-steely focus is singularly directed on her new assignment - accompany Henrik to recover the realms' source of light before the cosmos descends into chaos. While battling demons, dragons, and the not-quite dead, it becomes clear that immortality does not equal invincibility. And when Hel herself puts a hit on Brynn, the valkyrie has to decide if staying in control is worth losing everything for...or if it's time to rule the realms.
