Grave of Brothers (The Idun Trilogy, #3)

The Aegi are awakening.

Sparrow and Rome reunite in a world torn apart by Uriel's merciless attack. The people of Suhn fight to survive without Idun's rations, and without protection from the onslaught of new, uncontrollable Aegi. Anyone could go Berzerk. It's too late to undo the damage in Suhn, but as the Day of Light approaches, they are given one final chance to join forces against Uriel and prevent the End of Days.
