Clytie, a Valkyrie, finds herself questioning Odin's orders when Psyche comes for a shape-shifting panther, Storm. He rescues Clytie from a giant and something inside of her changes. A spark ignites, triggering an emotion Valkyries are forbidden to experience.
Following her new feelings, she turns her back on all she knows to be with Storm. However, she knows it's only a matter of time before Odin puts a price on their heads.
Odin furious with his Valkyrie for disobeying him, and proving the Well right, accepts the War is coming and Clytie will be the goddess who dethrones him, unless her sister stops her first.
