Astrid Irisdotter is a Valkyrie, a fierce warrior fighting to protect humanity from the evil god Loki and his brutal minions. She's on an urgent mission for her queen when everything goes hideously sideways. Undercover agent Luke Holden arrives on the scene just in time to save her life--and put his own on the line. Luke may have saved her, but that doesn't mean Astrid can trust him. Tempers flare as they hide secret upon secret from each other, but Astrid's inner warrior knows what it wants... and it will not take no for an answer.
