The Monsters Emerge - The Monsters Series, #2

Shadow is unaccustomed to life at court. Everything around her feels foreign-the Palace, the people, the fragile sense of security and peace. Eirho. Even her true name, the one that echoes through the corridors feels like it belongs to a stranger. For Shadow, normalcy lies in rage and ruin, chaos and panic. She knows blood, fire, and pain. But the anarchy she once knew is ready to return with a vengeance.
A new enemy strikes The City and everyone within its walls is clawed back into the depths of danger. This threat is unlike anything The City, or Shadow, has ever faced. A darkness that could drag them all to the pits of the earth veils the land, and an unknown enemy is at the front gates. Shadow needs to find a way to stop inevitable slaughter and her only chance is a clue. One name: The Eye. Everything and everyone is at stake; her magic may not be enough to save anyone. And this time, there may not be survivors.
