When Niasa heads out on her next assignment, she intends to follow her orders: Find the brutal, mindless warrior marked for Valhalla. As a Valkyrie, that's her duty. She's still in training and isn't allowed to choose for herself, though it hasn't stopped her in the past. While she watches her target fight gang members in a New York alley, a true hero shows up and changes her plans. Police cadet, Gus, is everything she believes a better warrior should be-smart, strategic, and honorable. When he dies heroically she ignores her orders and claims his spirit. What she doesn't realize is that someone has manipulated her and she's stumbled right into their hands. Now there are insidious forces trying to kill her and she has to find answers before she's too weak to cross the barrier back to Valhalla. Together with Gus, she'll discover dangerous secrets, including one about herself. Humanity is in danger, the realms are on the brink of war, and it's up to Niasa to fix it. If she survives long enough.
