After thousands of years of war, the peace agreement arranged by Emily forces the factions to work together to destroy a new threat. Tensions between Exavior and the Equites grow and Emily becomes a prime target. Chevalier struggles to come to terms with the friendships Emily has with the enemy factions, and when the Chief Enforcers go missing, he sets out to bring them back and tries to find a way to keep Emily out of the skirmish.

An important Equites trial puts Emily on the Council stand and shows her more of the volatile tendencies of the heku species. Exavior oversteps, throwing the Valle into action to protect the last Winchester, while a coup threatens to destroy their faction and pushes Emily’s ultimatum.

The Ferus emerge as a formidable enemy, and plans are made to extinguish the rogue band of heku. The V.E.S. begin experiments, threatning to expose the heku species, and only Emily can stop them.

A misunderstanding sends Emily out on her own and it will take all three factions to get her back. Will her time away cause a permanent rift between her and the Equites?
