When her soul is taken hostage, Effie loses what little magic she possessed. Now, in an effort to save herself, she and her group set out across the Arcanos for answers. Confronted with the blood magic of Nullam Sanguine, Effie realizes that the Arcanos are no longer as safe as she once believed, and Dellathians are no longer their only threat. The stronger she grows, so does her connection to the past. As more memories flood her consciousness about a life she isn't supposed to remember, Effie must make a choice about who to love and to what lengths she's willing to go to save innocent Arcani. When the Guardian of the lower realms offers her a deal, she has no idea what she's getting herself into-all for one little blue vial.
