As the alkins head back to Crossroads, Claudia leads her normal life, but not for long. Having a special soul, Claudia attracts danger, and she soon finds out who Gamma asked to watch over her. The Twelve, known as Divine Elders on Earth, are very much involved when they find out that Aliah, one of the God's first angels, escaped from the Abyss when the gates were opened by Aden. Needing Claudia's soul to escape the only place Aliah can reside - a place between Heaven and Earth - he sends his demons in search of all Claudia Emersons on Earth. Taking her soul will enable him to be released from Between and cross over to Crossroads, which would give him immense power.
As more secrets are revealed Claudia learns about the venators-nephilim, demon hunters. Now two opposing forces must work together in order to save Claudia and humanity from the most dangerous angel ever created. But along the way, trust becomes a big issue. Will love be enough to keep Claudia and Michael together? Who will make the ultimate sacrifice? Who will betray them all?
