Raven Romero lost the Sword of Souls, giving up the search for the only weapon that could kill Odin. Instead, she teamed up with human detective William Callahan to find the drug lord responsible for Venom - a narcotic leaving dead humans and supernaturals in its wake. But priorities change when a greater evil threatens Midgard and the only way to defeat it is with the sword. Being the humans' champion isn't easy, especially during withdrawal while trying to stay sober. And Raven is struggling with both. Enemies become friends and new enemies emerge as the hunt begins for The Sword of Souls.
